Project Overview

Project Update April 2020

The City of Ottawa will complete the Blair Road Widening for Transit Priority - Innes Road to Blair LRT Station – as a stand-alone Environmental Assessment (EA) Study in accordance with Schedule C of the Municipal Class EA as per the Ontario EA Act. The EA process will involve developing, assessing and evaluating alternatives, leading to a Recommended Plan. 

Project Update July 2019

Since the May 2018 Open House, the Project Team has received valuable input from the public, stakeholders, and NCC throughout the study period. Study activities to date are summarized below.

Geotechnical Investigations

The City received approval to access the NCC Greenbelt lands in December 2018 to undertake site investigations including borehole samples and geotechnical testing. Field work was completed in March 2019.

Expanded Scope and Study Area

The scope of the environmental assessment study has been expanded to include Blair Road widening for Transit Priority between Innes Road and the Blair LRT Station.

Brian Coburn Study Area July 2019

High Level Screening from 7 to 4 Options

A high level screening of the seven roadway and bus rapid transit options has been completed and four options are being carried forward for further assessment and evaluation. Further details of the high level screening are attached [ PDF 1.3 MB ]  The four short listed options are attached [ PDF 345 KB ]

Evaluation Criteria for the 4 Short Listed Options

The four short listed options will be assessed using evaluation criteria selected with input from the public, stakeholders, and in consultation with the NCC. The evaluation criteria fall within four groupings: Transportation and Transit, Natural Environment, Social / Cultural Environment and Cost. 

Attached [ PDF 1.2 MB ] are the evaluation criteria, rationale for the criteria and method of comparison.

Design Alternatives

Once the preferred roadway and bus rapid transit corridors have been confirmed, design alternatives will be identified and assessed considering:

  • Pedestrian and cycling infrastructure
  • Potential for high occupancy vehicle (HOV) lanes for buses and carpoolers
  • Cross-section design elements such as urban and rural
  • Grade separations/structures and
  • Storm drainage

Short-term affordable transit priority options are also being developed as part of the preferred solution.

Blair Road Transit Priority Design Options

The Project Team has commenced work on the Blair Road widening for Transit Priority between Innes Road and the Blair LRT Station. Design options to widen Blair Road for Transit Priority have been prepared and are attached [ PDF 400 KB ] 

Next Steps

The next round of consultations, including an open house is anticipated in the fall of 2019 to present the following:

  • Evaluation and assessment of the four roadway and bus rapid transit ultimate options and the recommended option
  • Recommended short-term and affordable Transit Priority solution (Chapel Hill Park and Ride to Blair Road at Innes Road)
  • Recommended design option for the Blair Road widening for Transit Priority.

Project Update May 2019

Since the May 2018 Open House, the Project Team has received valuable input from the public and stakeholders on this project. Recent study activities include:

  • The City received approval to access the NCC Greenbelt lands in December 2018 to undertake site investigations including borehole samples and geotechnical testing. Field work was completed in March 2019.
  • The Project Team met with NCC over the winter to obtain their input to the route options that impact the Greenbelt.
  • A screening is underway of the 7 Roadway / Transit options to a shorter list of options to carry forward for further assessment and evaluation.
  • Short-term affordable transit priority options are being developed as part of the preferred solution.

The scope of the study has been expanded to include Blair Road widening for transit priority between Innes Road and the Blair LRT Station as shown in the expanded study area. This expanded scope provides for a fulsome review of transit priority as busses within the study area are primarily destined to the Blair LRT Station.

The second Open House is anticipated to be in early Fall 2019 to present:

  • The screening of the 7 route options to a shorter list of options
  • Short-term affordable transit priority options (Blair Road to Navan Road)
  • Recommended long term and short term options (Blair Road to Navan Road)
  • Introduction of the Blair Road Widening for Transit Priority to Blair LRT Station EA Study
  • Blair Road transit priority options

The Environmental Assessment (EA) for the Blackburn Hamlet Bypass Extension (BHBPE) was completed and approved in 1999. The EA for the Cumberland Transitway was also undertaken at the same time as the BHBPE EA due to their proximity, particularly for the section from the Bypass to Mer Bleue Road (Figure 1).

 Blackburn Hamlet Bypass Extension

Figure 1: Recommended Alignments within Navan Road Corridor

Portions of the BHBPE (now called Brian Coburn Boulevard) have been built from Navan Road to east of Mer Bleue Road.  A recent geotechnical analysis concluded that the soil conditions in the vicinity of Navan Road to BHBPE section are very poor and the roadway would require considerably more funds to construct than previously estimated. The City is in search of a more cost-effective alternate corridor. Consideration must be given to any consequential changes to the adjacent future Cumberland Transitway.

Study Area

The EA study limits will extend from Blair Road to Brian Coburn Boulevard and south to Anderson/Renaud Road to allow for a larger range of alternatives to be examined. 

Brian Coburn study area

Figure 2: Study Area

Study Process

The study is being conducted in accordance with Ontario's EA Act, fulfilling the requirements of the Municipal Class EA process for Schedule C projects. The City must consider alternatives for the project, undertake public and agency consultation, assess the potential environmental impacts of the Recommended Plan and identify measures to mitigate any such impacts.

The study will also address potential implications of federal and National Capital Commission (NCC) properties and the need for federal approvals to implement the project.

As part of the study process, an Environmental Study Report (ESR) will be prepared for public review.

Get involved!

You are encouraged to participate in the study by attending consultation events or by directly contacting the study team with information, comments or questions. Updated project information will be posted periodically on the study website.

The study will also have the benefit of input from agency, business and public consultation groups that will meet at key points during the study.

Two open houses (minimum) will be scheduled throughout the study as an opportunity for interested persons to learn about the study and provide input. Notifications for the open house will be provided through local newspapers, e-mails to the study mailing list and postings on the website.

The City of Ottawa has initiated the Environmental Assessment (EA) study to develop an alternate plan for both the Brian Coburn Boulevard Extension and the Cumberland Transitway west of Navan Road. A recent geotechnical analysis concluded that the soil conditions in the area are very poor and it will be more costly than previously estimated to implement the previously approved 1999 EA Study Recommended Plans. As such, the City is in search of a more cost-effective solution.

What We Heard from Public Meeting #1

Will there be a presentation in French for the second Open House?
Yes, subsequent Open House presentations will include fully bilingual presentations.

Will the material presented for the second Open House have larger graphics and presentation?  
Yes, subsequent Open House material and presentations will use larger and clearer graphics and images.

Noise and vibration impacts need to be considered. How will this be done?  
Once the preferred Option has been selected, noise and vibration impacts will be reviewed. Noise sensitive areas, such as backyard living areas among others, will be identified. Changes in noise and vibration levels will be assessed and recommendations made based on the Ministry of the Environment and Climate Change and City of Ottawa Environmental Noise Control Guidelines.

Will property values decrease as a result of the bus rapid transit (BRT) and construction? 
As the construction will be occurring for a short period, it would not affect property value.

The traffic assessment needs to consider both existing and potential future traffic volumes on all area roads especially where congestion is already occurring. How will this be considered in the study?
The traffic model produced by the City and the Needs Assessment considered both existing and future travel demand. Future travel demand is based on the City’s Official Plan projections for population and employment to the planning horizon of 2031.

Will there be a new Option 7 considered along Renaud Road?
A new Option 7 will be developed and included in the evaluation. Option 7 would include extending and widening Renaud Road to 4 lanes and BRT along Renaud Road. See figure below.

Brian Coburn study area

What is the status of the Innes / Walkley / Hunt Club connection (IWHC)?
The IWHC connection will address growth and relieve congestion on Innes Rd. between Blair Road and Highway 417 as well as provide a connection between Orleans, Walkley and the Hunt Club area. Construction of this connection is identified beyond 2031 as per the City’s Transportation Master Plan (TMP).

Will Chapel Hill residents continue to have full access to Navan Road south of Brian Coburn Boulevard as well as the new Park and Ride?
The proposed cul de sac of Navan Road near Brian Coburn Boulevard in many of the Options shown will prevent access. The study team is refining the Options to avoid and minimize roadway closures. This is to ensure effective connectivity and access between communities and that other possible trip origins and destinations are maintained.

Will High-occupancy vehicle (HOV) lanes be included or considered as part of this study?
The study team will be considering HOV lanes as part of the interim and/or ultimate solution.

Why are BRT stops being considered along the Blackburn Hamlet Bypass?  
The BRT stops along the Blackburn Hamlet Bypass are currently identified in the City’s Transportation Master Plan. Once the preferred Option has been selected, transit stop locations will be identified based on ridership.

Will community impacts be given consideration as part of this study, including cut-through traffic, encroachment, noise and access? 
All of these factors will be taken into consideration in the evaluation of the different Options.

Will cycling and pedestrian facilities and connections be considered in the design of the preferred alternative?
Yes. The functional design of the preferred Option will include cycling and pedestrian facilities and connections as per City policy.

Video presentation scripts

Interim design

SLIDE 1 – Title Page

Welcome to this online consultation for the Brian Coburn Boulevard Extension and Cumberland Transitway Project Environmental Assessment Study. This second video provides an overview of the Recommended Interim Design for the study area as well as the overall project potential impacts and mitigation measures. The first video presented a project update; and the Recommended Ultimate Design.

SLIDE 2 – Environmental Effects and Mitigation - 1

The identification of potential project environmental effects is an important part of the EA study process and involves consideration of the various project activities and their interactions with the environment. Mitigation measures are identified to eliminate, reduce, control and/or offset the potentially adverse environmental effects.

As part of this project the development of a Landscape Mitigation Strategy is proposed to help address potential impacts to the Greenbelt’s natural and rural landscape.

Loss of vegetation / natural habitat will be addressed through an Ecological Restoration Plan to offset losses, enhance existing habitat quality and potentially identify new habitat features. Wildlife crossings and road exclusion fencing are also proposed to mitigate potentially increased wildlife mortality.

Impacts to fish and fish habitat will be addressed through various measures including a natural channel design at the proposed realignment of Mud Creek. Fish passage and natural channel flow regimes are proposed to be maintained at culvert water crossings.

SLIDE 3 – Environmental Effects and Mitigation - 2

Loss of wetland function is another potential environmental effect, particularly given the project’s proximity to the Mer Bleue Wetland. To address this risk, it is proposed that an Ecological Restoration and Enhancement Plan be prepared. The Plan will address management of invasive species, installation of key habitat features, contingency measures and adaptive management.

Surface water quantity control and quality control are also areas of concern. It is proposed that water quantity control (post to pre-development) and erosion threshold protocols be followed as general stormwater criteria through the detail design process. An enhanced water quality target of 80% Total Suspended Solids removal will be required for water quality treatment. As part of the Mud Creek realignment natural channel design, it is proposed that measures such as roots wads/live stakes be considered for bank stabilization and water quality improvements.

Regional climate related hazards identified for the project include increased extreme heat days, increases in peak stormwater runoff, and projected changes to average temperature, and water balance (drought) cycles. It is recommended that climate change adaptation measures be considered during detail design including those related to flood design, stormwater management, selection of plant species for landscaping and erosion protection. It is also proposed that sustainable design principles be followed including consideration of low carbon material selection.

SLIDE 4 – Environmental Effects and Mitigation - 3

Approximately 44 hectares of property will need to be acquired from the NCC.

Removal of 2 NCC owned buildings (one residence and one shed) will be required for construction of the Transitway. Up to 3 additional NCC owned residences may be affected along the south side of the new roadway although design modifications will be considered to avoid having to remove these buildings. Mitigation or compensation will be required.

Construction of the Transitway will block Weir Road and result in loss of access to the community gardens. Opportunities will be explored for the potential relocation of the community gardens.

Increased noise levels in noise sensitive areas are proposed to be addressed through provision of noise attenuation walls, where warranted and feasible.

Temporary construction nuisance, such as dust, noise, and delays, will be mitigated through standard construction contract provisions.

SLIDE 5 – Interim Plan for Transit Priority / HOV Overview

This is an overview of the Recommended Interim Design which includes widening of Innes Road from 6 to 8 lanes to accommodate one shared Transit Priority / High Occupancy Vehicle (or HOV) lane per direction from the west end of the Blackburn Hamlet Bypass to east of Blair Road, a distance of approximately 2.0 km.

The existing on-road bicycle lanes are proposed to be replaced by a new north side 4.0 m multi-use pathway to accommodate Active Transportation users and serve as a bi-directional cycling facility. The new multi-use pathway will extend from Blair Road at Innes Road to the Tauvette Street / Glen Park Drive / Innes Road intersection in Blackburn Hamlet.

Property access will typically be limited to right-in/right-out access except at intersections with traffic control signals.

New Transit only queue-jump lanes will be provided on each leg of the Navan Road / Blackburn Hamlet Bypass intersection.

SLIDE 6 – Recommended Typical Cross-Section

The Typical Interim Cross-Section is shown facing towards the east (just east of Mud Creek). The existing urban (curbed) cross-section is maintained by keeping the existing raised median and lanes intact and a widening to the outside by relocating the north and south curbs by 1.5 metres. The width of property required to accommodate the north multi-use pathway varies between 2 and 7 metres.

SLIDE 7 – Interim Plan for Transit Priority at Blackburn Hamlet Bypass and Navan Road

The Interim Plan proposes that new Transit only queue-jump lanes be provided on each leg of the Navan Road / Blackburn Hamlet Bypass intersection to help buses avoid congestion at these locations. A new multi-use pathway connection, shown in blue with a preliminary conceptual location, is proposed between the intersection and Cleroux Crescent to the north.

SLIDE 8 – Interim Plan for Transit Priority / HOV – Blackburn Hamlet Bypass & Innes Road (West) Intersection

The new shared Transit Priority / HOV lanes on Innes Road are proposed to commence at the western limit of the Blackburn Hamlet Bypass and continue to the west. The multi-use pathway that will be added to the north side of Innes Road will connect to Blackburn Hamlet via Pepin Court. A 3.0 m high noise attenuation wall is proposed along the south side of the residences located on the south side of Pepin Court.

SLIDE 9 – Interim Plan for Transit Priority / HOV – at Church Property

This slide shows the proposed Interim Plan for shared Transit Priority / HOV Lanes along Innes Road from west of the Bypass to Anderson Road. The proposed multi-use pathway is shown along the north side of the corridor. New traffic control signals are proposed at the church property located at 2214 Innes Road.

SLIDE 10 – Interim Plan for Transit Priority / HOV at Blair Road

This slide shows the west limit of the Interim Plan at the Innes Road / Blair Road intersection. The shared Transit Priority / HOV Lanes on Innes Road will commence just east of Blair Road. The proposed multi-use pathway along Innes Road will connect to Blair Road with access to the future multi-use pathway along the west of Blair Road and the east side paved shoulder as identified in the recently completed Blair Road Transit Priority Environmental Assessment Study.

Ultimate design

SLIDE 1 – Title Page

Welcome to this online consultation for the City of Ottawa’s Brian Coburn Boulevard Extension and Cumberland Transitway Environmental Assessment Study. This video provides an overview of the Recommended Ultimate Design for the Brian Coburn Boulevard Extension and Cumberland Transitway. A second video presentation is available, which presents the Recommended Interim Design, including the provision of shared transit priority and high-occupancy vehicle lanes along Innes Road as well as potential environmental impacts and mitigation measures for both the recommended ultimate and interim plan.

SLIDE 2 – Purpose of Consultation

The purpose of this on-line consultation process is to:

  • Provide a project update
  • Present Recommended Designs for both the Ultimate and Interim Phases
  • Present potential environmental effects and recommended mitigations
  • Invite comments and feedback on the project
  • Explain the next steps in the Environmental Assessment process

SLIDE 3 – Project Update

This Environmental Assessment Study is nearing completion. Since the last public consultation, the study team has selected a technically preferred corridor, and developed and assessed several design options for the corridor alignment to determine a Recommended Ultimate and Interim Design.

The Recommended Ultimate and Interim Designs address the needs of the study area for two project horizons: with the Ultimate Phase beyond the 2031 timeframe and the Interim Phase within the 2031 planning horizon and based on affordability.

Since the last open house in November 2019, the Blair Road Transit Priority Environmental Assessment Study has been made a stand-alone project. More information on the recently completed Blair Road Transit Priority Corridor Environmental Assessment Study is available by visiting the City’s website at www.ottawa.ca/blairroad

SLIDE 4 – Environmental Assessment Process

This project is being conducted in accordance with Ontario's Environmental Assessment Act, fulfilling the requirements of the Municipal Class Environmental Assessment process for Schedule C projects. The Class EA process includes five phases with Phases 1 through 3 now substantially complete.

The graphic illustrates that following this round of consultation, the recommended functional design will be finalized, and documentation will be prepared for public and agency review to complete the study phase of the process.

SLIDE 5 – Short-Listed Corridor Options

As presented at the last open house, four short-listed corridor options were evaluated to determine the preferred corridor. All four options include both a bus rapid transit facility, which is part of the future Cumberland Transitway – shown in blue and a new or widened roadway shown in red from Navan Road at Brian Coburn Boulevard westerly to, respectively, Blair Road for the Transitway and the future Innes-Walkley-Hunt Club arterial roadway corridor for the roadway. Widening of Blair Road and an extension of the rapid transit corridor parallel to Blair Road north to the Blair LRT Station are not part of this project and are shown for reference only.

  • Option 1 was determined to have the highest impact on farms and higher amounts of habitat fragmentation. It has some Greenbelt Core Natural Area impacts but is further from Mer Bleue and associated wetlands.
  • Option 4 was determined to have the least impact on farms, higher habitat fragmentation, the highest impact on private property, highest potential impacts on heritage, air quality, noise, and vibration impacts on sensitive (residential) land uses. It has some Greenbelt Core Natural Area impacts but is further from Mer Bleue and associated wetlands.
  • Option 5 severs more farm parcels, has the highest habitat fragmentation, impacts on potential Species at Risk habitat and on views/vistas. It has some Greenbelt Core Natural Area impacts and is close to Mer Bleue and associated wetlands.
  • Option 7 was determined to be the technically preferred Option in the evaluation and is being carried forward. Comparatively speaking, benefits of Option 7 include:
    • Best relative performance for Transportation and Transit factors
    • Provides the most direct route between South Orleans and Ottawa’s South urban area and addresses this travel demand
    • Reduces traffic on Anderson Rd when fully implemented with the IWHC link.
    • Least amount of encroachment into Greenbelt Core Areas
    • Least number of private and federal land parcels potentially impacted, including farmlands
    • Least potential impact on views and vistas and the Greenbelt experience
    • Lowest relative cost of construction.

As we continue through this presentation, potential environmental impacts and mitigation measures will be discussed.

We note that on August 25, 2020, the NCC Board of Directors affirmed its position that federal lands required to implement the Brian Coburn Boulevard / Cumberland Transitway extension alignment Options 5 and 7 will not be made available.

SLIDE 6 – Recommended BCBE / CTW Ultimate Design

This is an overview of the Recommended Ultimate Design for the Brian Coburn Boulevard Extension, approximately 6.1 km in length, and the Cumberland Transitway, approximately 6.5 km in length.

Beginning in the east, the project connects to the Chapel Hill Park and Ride in the northeast corner of Brian Coburn Boulevard and Navan Road. Over most of the project limits, the bus rapid transit (BRT) corridor is located along the north side of the recommended right-of-way, with the recommended roadway and multi-use pathway generally located immediately to the south to reduce overall project footprint and environmental impact.

Various design alternatives were considered for the project, particularly in more technically challenging areas such as the area of the Mud Creek crossing. The design alternatives were assessed based on their ability to accommodate active transportation, maintain traffic operations, preserve the National Capital Commission (NCC) Greenbelt rural features, mitigate potential loss of identified ecological functions, avoid areas of unstable slopes and defined flood zones, and with due consideration of social environmental effects including noise.

Four Gateway locations, with opportunities for landscaping enhancements, are identified at the intersections of Brian Coburn Boulevard Extension with Navan Road, Renaud Road, Anderson Road, and the future Innes-Walkley-Hunt Club Connection. Gateways will help create an identifiable character along pathways to enhance the user experience.

SLIDE 7 – Typical Ultimate Cross-Section (BCBE-CTW)

The Typical Ultimate Cross-Section is shown facing towards the east and includes both the two-lane Cumberland Transitway (BRT) and the four-lane Brian Coburn Blvd. Extension. A narrow (1.5 m) raised median is proposed to separate the eastbound and westbound lanes on Brian Coburn Blvd. to improve safety and will result in modified right-in / right-out property access along the corridor.

To minimize the project’s footprint, the new transit and arterial roadway corridor will make use of the existing east-west section of Renaud Road and the existing section of Anderson Road northwest of Renaud Road.

A paved 3.0 m multi-use pathway is proposed along the south side of the corridor to accommodate Active Transportation users and serve as a bi-directional cycling facility. A rural (ditched) cross-section will match with the existing rural conditions. Context sensitive planting is recommended along the outer edges of the Transitway and roadway and will maintain existing views and vistas.

Based on the above, the right-of-way for all three transportation elements can be 77.0 metres or wider. The next phase of the project (detailed design) will examine how this width can be reduced.

Key features of the design at specific locations along the corridor will be discussed in the next few slides.

SLIDE 8 – Recommended Ultimate Alignment – Near Chapel Hill Park and Ride

The Transitway (BRT) and Brian Coburn Blvd. will match to existing conditions between Navan Road and Pagé Road. A bus-only connection will be provided from the Transitway to and from the Chapel Hill Park and Ride and a new on-line transit station will be added at this location and will include a grade-separated accessible pedestrian/cycling overpass structure.

The Transitway will pass under Navan Road via a new bridge structure while Brian Coburn Boulevard will be extended to the west of Navan Road down an embankment to the elevation of the lands below the escarpment.

The existing roundabout at Brian Coburn Boulevard and Navan Road will be expanded to a two-lane roundabout and multi-use pathways will be added to ensure convenient community access to the transit station. These will include a direct pathway connection from Percifor Way to Navan Road. Noise attenuation barriers, 2.8 metres in height, are proposed along the north side of Bradley Estates and along the south edge of the residential property at 2870 Navan Road.

SLIDE 9 – Recommended Ultimate Alignment – Renaud Road Intersection and NCC Trail and Farm Access

The new road and Transitway (BRT) will extend from Navan Road to Renaud Road through existing farmland in close proximity to the existing hydro corridor to bundle both corridors and minimize the project footprint.

A protected signalized intersection will be provided at the new Brian Coburn Blvd. and Renaud Road intersection and will include multi-use pathway crossings on the south and west legs of the intersection.

In this area the separation of the Transitway (BRT) and roadway corridor increases to accommodate a north-south multi-use pathway under the Transitway as well as farm vehicle access to connect to a proposed NCC pathway and to serve existing farmland to the north. The north-south multi-use pathway will also extend to the south to connect to the existing Prescott-Russell Trail. In this area, a realignment of Renaud Road is proposed to eliminate a very sharp roadway ‘bend’ as well as two roadway/trail crossings.

SLIDE 10 – Recommended Ultimate Alignment – Mud Creek Realignment

In the area of the existing Mud Creek crossing, the Transitway (BRT) and roadway corridors return to their minimum possible separation. An approximately 300 metre long realignment of Mud Creek is proposed in this area and provides an opportunity to improve existing creek conditions through natural channel design, terrestrial and aquatic habitat enhancements, erosion protection and slope stabilization measures. The multi-use pathway is proposed to pass over the realigned creek on its own pedestrian bridge.

SLIDE 11 – Recommended Ultimate Alignment – Anderson Road Intersection

The existing roundabout at Anderson Road is proposed to be replaced with a protected signalized intersection with the new roadway and will include a multi-use pathway crossing on the south side of the intersection.

Construction of the Transitway will block Weir Road and result in loss of access to the community gardens. Opportunities will be explored for the potential relocation of the community gardens. A 2.5 m high noise attenuation barrier is proposed along the south side of the road right-of-way between Maurice Street and Ida Street.

Two NCC buildings will likely need to be removed along the north side of existing Renaud Road in this area to accommodate the transitway. Design modifications will be explored to avoid encroachment on, and possible removal of three NCC buildings along the south side of existing Renaud Road and Anderson Road in this area.

SLIDE 12 - Recommended Ultimate Alignment – Connection to IWHC and Blair Road

West of the proposed new Anderson Road intersection with the Brian Coburn Blvd. extension, the existing Anderson Road will be closed to accommodate the transitway. The transitway will follow the existing Anderson Road alignment and pass under Innes Road via a tunnel and then continue west following the north edge of Innes Road to Blair Road. In this area the new roadway and multi-use pathway will extend west through existing Greenbelt farmland to connect to a protected signalized intersection with the future Innes-Walkley-Hunt Club arterial roadway link. Although not part of this project, the EA study for the future Innes/Walkley/Hunt Club link was previously completed in 2008.

A future multi-use pathway, shown in blue, is proposed to connect north to Innes Road and will extend along the south side of Innes Road to Blair Road. Some widening of Innes Road is required to accommodate the proposed Transitway and multi-use pathway although it is not anticipated that the existing bridge structure at Greens Creek will need to be extended.

SLIDE 13 – Next Steps / Proposed Timelines

The next steps for this study include:

  • Review comments received through the on-line consultation.
