Stage 2 Confederation Line West Extension Spring 2020 Update

Stage 2 Confederation Line West Extension Spring 2020 Update

Overview

Work is underway to extend the Confederation Line west from Tunney’s Pasture Station to Baseline Road and Moodie Drive. In 2020, crews will be focusing on the Parkway and Connaught cut-and-cover tunnels.

The Confederation Line West Extension will include two cut-and-cover tunnels.

The City of Ottawa’s Rail Construction Program is closely monitoring the COVID-19 situation and is in contact with the constructors about adhering to guidance provided by Ottawa Public Health and the Province of Ontario. Should there be any changes to this work, it will be communicated to the public.

Here is what construction you can expect to begin or occur in 2020:

Tunney’s Pasture Area 

A new bridge will be constructed west of Tunney’s Pasture this summer. The Goldenrod Bridge will span over the transitway connecting the north and south sides, across from Smirle Avenue. Temporary pedestrian detours are expected during construction, along the south side multi-use pathway (MUP).

Sir John A. Macdonald (SJAM) Parkway Realignment 

In spring 2020, work resumed to shift the Sir John A. Macdonald Parkway north between Dominion Avenue and Cleary Avenue. This will allow for future construction of the cut-and-cover tunnel to safely occur on the south side of the Sir John A. Macdonald Parkway without interfering with traffic.

After completing the temporary westbound lanes last fall, crews have started to construct the temporary eastbound lanes with excavation, drainage and grading taking place this spring. This work will be followed by paving and curb installation this summer. These new traffic lanes will bypass tunnel construction which is anticipated to begin later this summer.

Traffic will be maintained although delays may occur at times. Intermittent lane closures will be required at times. Motorists should be aware of and adhere to traffic control signage, posted speed limits and traffic control personnel.

Parkway Cut and Cover Tunnel Construction

The Confederation Line West extension will travel between Dominion Station and Lincoln Fields Station via the Parkway Tunnel. This 4-kilometre tunnel will be constructed using the cut-and-cover excavation method. The tunnel will be excavated from the surface. Once the tunnel floor, walls, and roof are constructed with steel and concrete, it will be backfilled to previous conditions at surface level.

Sir John A. Macdonald Corridor

Cut and cover construction is expected to begin in late summer in the SJAM corridor. This area will see more truck activity as hauling of excavation will be ongoing until winter.

Pedestrian and cyclist access to the SJAM Parkway and use of the north side pathway will be modified with detours but accessible throughout construction. Please note, the pathway on the south side of the SJAM Parkway will close in summer 2020 as tunnel construction begins.

Pedestrian and cyclist connectivity to the SJAM Parkway will be improved following Stage 2 construction. A new pedestrian underpass will be constructed at Churchill Avenue North in two phases over the course of two years beginning this summer with the underpass of the eastbound lane. Pedestrian underpass construction at Cleary Avenue and rehabilitation of pedestrian underpasses at Lanark Avenue and Carleton Avenue will start after the tunnel construction.

The Rochester Field area will be used for several years as a construction site, access area, and equipment laydown while crews work on the cut and cover tunnel. Activity will increase in and around Rochester Field starting in June. Trucks will be using this corridor from Richmond Road to the SJAM Parkway as an access route. In August, an onsite facility will be set up along the SJAM Parkway that will process and dry the excavated material from the tunnel in slurry pits. Slurry is a mix of dense materials and liquid, which is dried in pits in the ground. This dry material can then be transported or used afterward. There will also be concrete mixing occurring here. This will begin operation in September and will be within an enclosed area.

Byron-Richmond Corridor

Before tunnel construction can begin, crews will be relocating existing sewers, hydro, and telecommunication infrastructure within the Byron Linear Park corridor. Utility relocations have already begun and are expected to be completed in stages, allowing tunnel work to begin.

Fence installation surrounding Byron Linear Park will begin in spring 2020 closing Byron Linear Park. Residents are asked to respect construction fencing and signage. In late May, a new sidewalk will be constructed on the south side of Byron Avenue, between Richmond Road and Redwood Avenue. During the phases of construction in this area, there will be a reduction of on-street parking spaces. Modifications to road alignments will be in place to accommodate the work in the Byron-Richmond corridor which is required as cut-and-cover tunnel construction advances. Pedestrian access will be maintained with detours around the work zone.

Work will begin early this summer to establish equipment laydown areas in McEwen Park and in Lincoln Fields. The future New Orchard Station site will be excavated starting this summer. MUPs connecting Lincoln Field park with Richmond Road will be relocated to maintain connectivity. Increased activity from trucks, crews and equipment will start this spring and be ongoing along the alignment throughout the project’s construction.

Traffic will be maintained although delays may occur at times. Intermittent lane closures will be required at times. Motorists should be aware of and adhere to traffic control signage, posted speed limits and traffic control personnel.

Lincoln Fields Station 

Work at Lincoln Fields is well underway to relocate a storm sewer that conflicts with the future station and guideway. A new MUP has recently been constructed to maintain pedestrian and cyclist connectivity throughout construction. Note that occasional detours and delays may be experienced throughout the course of the project, and flag persons will be in place to direct mobility.

Laydown areas for crews and equipment will be situated in Lincoln Fields. Carling Avenue at Lincoln Fields will also undergo utility work that will temporarily detour pedestrians and have traffic lane reductions. Sidewalk closures of one side on Carling Avenue will take place to shift pedestrians temporarily as crews work on utilities, and as one side closes the opposite sidewalk will be used, this will occur intermittently for several years.

A temporary bus loop will be built in June, to maintain public transit throughout construction. After this work is completed, construction will start on the Lincoln Fields temporary bus facility and then on the Lincoln Fields Station.

Work in the Carling Avenue and Lincoln Fields area will be ongoing for several years. There will be periodic requirements for nighttime construction work which will require Noise Exemption Permits.

Iris Station to Baseline Station 

Construction has been underway at Iris Station since early spring and will continue through the year with excavation, silt fence installation, and utility work in support of two new culverts for the realignment of the Pinecrest Creek from the east to the west side of the Transitway. One culvert will be installed under the future guideway, south of Iris Street, and the other culvert will be constructed underneath Iris Street, west of the Transitway. Culvert construction will begin in the spring of 2020 and continue into 2021. Traffic and bus service through the area will be maintained throughout construction. The roads will be re-aligned to bypass construction.

The culverts for Pinecrest Creek will be constructed at the future Iris Station site starting in May, which will see crews and drilling equipment to build supports. Starting in June, a temporary bus detour road for both directions along the Transitway will be constructed, until end of August.

While Baseline Station construction does not start until 2021, preparatory work for the adjacent Bus Operator Building began in April. Ground preparation and equipment setup are currently underway with facility construction anticipated to begin in June. Utility work at this site will occur from June through August.

Lincoln Fields Flyover Rail Bridge

South of Lincoln Fields Station, Moodie-bound trains will travel across a section of elevated rail known as the Lincoln Fields Flyover Rail Bridge before entering the Connaught Cut-and-Cover Tunnel. This is where the Confederation Line West will branch off towards two terminus stations: Moodie Station and Baseline Station. Work began this spring on the flyover bridge foundation with the drilled shafts and support pier construction which will continue through the fall.

The flyover bridge for the train will be built up to the existing pedestrian bridge crossing the Transitway. Once the new pedestrian bridge is built in 2021, the remainder of the flyover bridge will be completed.

Fencing will be in place around the work site for safety, as well as silt fencing for environmental protection. The MUPs within the park will be kept accessible for use by pedestrians, however temporary detours will be put in place to accommodate construction on the east side of the Transitway. Crews, vehicles and equipment will be accessing the park through the Hanlon Avenue right of way. This summer, a gravel access road will be constructed within Connaught Park from the SJAM Parkway on-ramp, diverting most construction traffic from local streets. This access road is going to cross the multi-use pathway at 1-2 locations and will be managed via stop signs and/or flaggers.

Connaught Cut-and-Cover Tunnel to Queensview Station 

Preliminary work for the Connaught cut-and-cover tunnel has begun. Crews must relocate utilities that are currently in conflict with the tunnel alignment. Temporary widening of Connaught Avenue will need to take place at the intersection of Connaught and Hanlon, along with streetlight relocation. Traffic control measures such as temporary concrete barrier installation is required on Connaught Avenue, creating some lane reductions in this immediate area. Minor traffic delays can be expected periodically during the daytime hours, but access will be maintained in the area for all vehicle, cycling, and pedestrian traffic.

Construction work along the Connaught Tunnel will require an increase in construction trucks and equipment in the wider area, utilizing routes through Connaught Park to Carling Avenue, and along Connaught Avenue to Queensview Drive, near the OC bus facility. The local baseball diamond will be closed during construction and used as a laydown area for the coordination of construction activities throughout the duration of the project.

Queensview Station 

Work has begun on excavation of the land just south of the OC Transpo facility, to the limits just north of Highway 417, west of Connaught Avenue, as crews begin clearing and levelling the area.

Utility work including relocation of storm and sanitary lines will occur from spring 2020 through spring 2021. The driveway between OC Transpo’s facility and Connaught Avenue will be temporarily relocated to the north, out of the way of this utility work, and future cut and cover tunnel construction. Towards the end of the project it will be reinstated to the original location.

Pinecrest Station Area 

Stormwater and sewer line relocation will occur this summer, at the Pinecrest interchange in order to begin work on the future station. Preliminary excavation for a new bridge at Pinecrest Road will also begin this summer.

New highway interchange ramps are required to create space for the new station and for a bus loop; removal of the old ramps will follow. Equipment will be moved into the area late summer, as crews move westward from the Connaught and Queensview Station areas. For more information regarding upcoming modifications to Highway 417 ramps, please see the Summary of Highway 417 Ramp Modifications section below.

Pending Ministry of Transportation of Ontario (MTO) approvals, site preparations will begin north of Highway 417, on the east and west sides of Pinecrest Road. A new bridge for the southbound Pinecrest to Highway 417 westbound on ramp will be built. The ramp must be shifted outward to accommodate the future Pinecrest Station and LRT tracks underneath. Short term closures of the existing ramp may be required in order to build the replacement ramp, along with work on the existing Pinecrest Road bridge. A temporary shift of the westbound Highway 417 to Pinecrest Road off ramp is also required to accommodate the new LRT.

As designs advance for this area, and approvals are received from the province, more details will be provided on Pinecrest Station and the Pinecrest interchange with Highway 417.

Bayshore Station to Moodie Station, and the Light Maintenance and Storage Facility (LMSF)

Work will begin on the Holly Acres rail-over-road bridge later this summer, pending MTO approvals, through to 2021. Preparatory works will begin this summer followed by the construction of piers and retaining walls. Construction of the bridge deck will occur in 2021.

Third-party utility relocation will occur in the area of Moodie Drive prior to the commencement of station construction in May through June. Excavation for the new northbound Moodie to Highway 417 westbound and southbound Moodie to Highway 417 westbound ramps will begin later this summer. Ramp work is required to accommodate the LRT track alignment and station construction.

Construction of the Moodie Light Maintenance and Storage Facility is underway west of Moodie Drive, north of Highway 417, and south of Corkstown Road. Excavation and utility relocation are ongoing in preparation for upcoming 2021 foundation work east of Moodie Drive. Corkstown Road will be relocated for construction of the Moodie bus station terminal.

  • Eastbound Highway 174 to Pinecrest Road off-ramp detour

In order to avoid impacting peak traffic hours, there will be ongoing night work at locations from Moodie to Tunney’s Pasture, and Baseline to Iris. The project is sensitive to work near residential areas and will manage work to minimize impact to residents.Hours of Work [Heading 1]

Motorized equipment and vehicles used on the project are equipped with white noise-type broadband back-up alarms, which are much less disruptive to surrounding communities than older versions of these safety alarms.

Night work can only occur with a valid City of Ottawa Noise By-law Exemption permit, which is obtained or renewed for a maximum of 90 days at a time.

Monitoring devices for sound and vibration levels will be placed in multiple areas to make sure levels do not exceed pre-determined project limits. Devices will be placed on public and private property, with owner consent, in key work zones to be able to monitor close to residences and businesses, to keep work within limits.
