OR 174 and CR 17 were formerly Provincial Highway 17 and were transferred to the municipalities in 1997.
City of Ottawa has planned 174 improvements:
- 2009 to 2015 Widen from 5 to 6 lanes from Highway 417 to Blair Road
- 2016 to 2022 Widen from 4 to 6 lanes from Blair to Jeanne d’Arc Blvd
- Transportation problems (congestion and safety) have been identified for many years
- Natural geographic constraints (e.g., Ottawa River and Mer Bleue Bog) limit the alternative east-west transportation routes
- OR 174/CR17 is the only high capacity arterial in the area
- Growth in Orléans, Cumberland and Rockland has continued to increase traffic volumes
The United Counties of Prescott and Russell, in partnership with the City of Ottawa, have initiated a Schedule C Class Environmental Assessment study for the roadway.
Planning and environmental assessment process
In accordance with the Municipal Class Environmental Assessment (2011), the widening of a road or construction of a new road/paved facility over $2.3M is a Schedule “C” project. Schedule “C” projects require the preparation of an Environmental Study Report which will be made available for public review.
Effective consultation will play a key role in the success of this project. Three separate Consultation Groups representing various agency, business and public stakeholders, will provide direct input and feedback during the course of the study.
Consultation with the following groups is occurring throughout the study:
Agency Consultation Group (ACG), comprised of representatives from federal, provincial, municipal and other approval authorities and agencies.
Business Consultation Group (BCG), comprised of representatives from local businesses, business associations and institutions.
Public Consultation Group (PCG), comprised of representatives from city councillors, community associations and special interest groups.
The general public will have the opportunity to build awareness, knowledge and understanding of the study through:
- Public open houses and presentations
- Media coverage
- Newspaper notices
- Study reports
- Comment sheets-questionnaires
- Written submissions
- Study website and email

Needs assessment overview
Transportation problems in the area have been identified for many years. The Needs Assessment for this study has reviewed previous reports and utilized new information to assess:
- Existing and future transportation (road and transit) capacity
- Safety improvement opportunities
- Impacts of new developments and expanded urban areas
- Increasing traffic volumes between 1988 and 2031
- Capacity of the road has been exceeded when the volume bars are above the capacity lines
Needs assessment – Capacity
A key component of the study was to evaluate the need to provide transportation infrastructure in the Study Area to meet the current and future transportation requirements.
The analysis considered:
- Existing travel conditions at key interchanges and specific screenlines
- Various travel modes across these screenlines
- Targets for transit and other non-auto travel modes in the relevant Official Plans
- Future travel conditions related to population growth targets
- Future vehicular volume capacities of the screenlines
- Strategies to address deficiencies in screenline capacity
There is a need to provide additional transportation capacity.
Needs assessment – Safety
Another key component of the study was to evaluate safety concerns.
The analysis of 174/17 considered:
- Review of existing safety reviews and reports
- Split to Trim – 1487 collisions
- Trim to Canaan – 465 collisions
- Canaan to Landry – 287 collisions
- Comparison of the predicted number of collisions for a similar type of roadway and the expected number of collisions based on actual collision experience and statistical analysis
- Significant contributors to collision experience:
- Speed, roadside character, access, interchange and intersection geometry, lighting, positive guidance, passing opportunities, accommodating transit
Existing conditions overview
Baseline environmental conditions were documented to provide a foundation for assessing how the environment might be affected by a transportation facility. The information will be used to:
- Develop reasonable alternatives
- Identify impacts
- Evaluate alternatives
Information will be updated, as necessary, as the study progresses and more detailed information is required.

Business condition assessment
The most prominent business type along the OR 174-CR 17 corridor is retail, followed by food, fuel and accommodation outlets.
There is a higher concentration of businesses in Gloucester and the City of Clarence Rockland than in Orléans and Cumberland.
Most prevalent business type:
- Gloucester - Offices or Professional Services
- Clarence Rockland – retail
Only a small proportion of businesses are primarily served by passing traffic.
There are capacity, safety and operational deficiencies in the study area.
- Predicted traffic volumes are expected to exceed operational standards at the majority of key road crossings even with an increased transit ridership
- An arterial-type lane is required in each direction to provide additional capacity in 2031 from Highway 417 to Rockland
- There is potential for safety improvements in site-specific areas where higher than predicted collisions occur
In order to address these deficiencies a long list of alternative solutions was developed.
- Do nothing
- Enhance other modes and/or manage travel demand
- Improve the existing corridor with transportation systems management (TSM)
- Split to Trim Road: add interchange at Trim Road
- Trim Road to Rockland: improve transition zone cross-section; improve intersection at bottlenecks such as Cameron Street in Cumberland, Quigley Hill Rd, Old Montreal Rd, Canaan Rd, Laurier Street and Landry Road; consolidate private laneways to one or more service road(s) from Meadow Lane Road to Quigley Hill Road; add passing lanes and/or reversible lanes
- Provide additional road capacity
- Expand the 174/17 existing corridor
- Split to Trim Road: widen freeway from 4 to 6 lanes
- Trim Road to Rockland: widen arterial from 2 to 4 lanes
- Expand other east-west arterial roads such as Old Montreal Road, Wilhaven Drive, Frank Kenny Road, Trim Road and Innes Road
- Construct new east-west roads:
- From Trim Road easterly up the escarpment to south of Wilhaven Drive to Baseline Road to Landry Road
- At Rockland, southerly bypass of existing development
- Combination of the above solutions
Screening of alternative solutions
Screening criteria were developed to assess the merits of the long list of alternative solutions.
The screening criteria are:
- The ability of the alternative to address the project need. Alternative solutions must provide transportation capacity and improve safety
- Adherence to policies, regulations, and local standards of practice. Alternatives should not contravene provincial/federal policies or municipal regulations or policies
Consideration of environmental impacts. Alternatives were reviewed to determine their high level impacts on the various environmental conditions. The ability to avoid /reduce /minimize impacts was considered
Screening of alternative solutions strategies
- Measures on their own do not address need
- TDM measures included as part of overall solution
- Passing lane don’t address capacity needs. Not carried forward
- Reversible lanes applicable to lower speed urban locations. Not appropriate for rural areas. Speeds and driveways create unsafe conditions for motorists and residents. Not carried forward
- Other TSM measures included as part of overall solution
|Do Nothing||Does not address the need|
|Transportation Demand Management (TDM)||Does not address the need|
|Transportation Systems Management (TSM)||Does not address the need|
|Additional road capacity||May address the need|
|Combination of alternatives||May address the need|

Shortlist of alternative solutions
We will refine the short list of alternatives and undertake a more detailed evaluation of the impacts and benefits of the alternative solutions carried forward to arrive at a preferred alternative solution.
- Widen existing 174 to 6 lanes
Trim to Rockland
- Widen existing 174/17 to 4 lanes
- Widen/new route Innes-Baseline
- Build new route south of Wilhaven
- Improve existing 17
- Build new route south of Rockland
The methodology of evaluating alternative solutions will address the following objectives. Evaluation of alternative solutions carried forward
- Use of Criteria: Criteria/indicators (i.e., features or considerations) should be used as the basis for the evaluation of the alternative solutions
- Weighting or Ranking of Criteria: An ordering (i.e., weighting or ranking in terms of importance) of the criteria should be the basis for the evaluation
Sensitivity Analysis: Some form of sensitivity analysis should be completed as part of the evaluation process (i.e., to test the results of the evaluation and to verify the influential factors in the results of the evaluation)
Examples of evaluation criteria
Evaluation criteria are specific factors or considerations which are used to compare alternatives. Factors that need to be considered in a development of criteria include:
- The nature of the project
- The expectations of stakeholders
- An understanding of the existing conditions
- The delineation of boundaries
- The issues related to the proposed project
The study team will develop the criteria to be used in this assessment with the stakeholders.
Let us know what you think is important and should be considered in the selection of an alternative.
Examples of Criteria
• Community Linkages
• Economic Activity
• Land requirements/use
Transportation & Infrastructure
• Transit Ridership
• Network/System Integration
• Level of Service
• Capital Cost
• Operational and Maintenance Costs
• Business Impacts
The next steps in the study process are to:
- Evaluate the Alternative Solutions carried forward
- Identify a preliminary preferred solution
- Confirm the preferred solution and review the EA Requirements
- Develop Alternative Design for the preferred solution
- Update existing conditions, as required
- Continue to meet with the Consultation Groups
The results will be presented at Public Open House #2 scheduled for the fall of 2013.
