The Dundas BRT - Pinch Points - Cooksville Area

← Return to the Dundas BRT map

Cooksville Pinch Point

A median BRT route in the Cooksville area is in a constrained right-of-way from Confederation Parkway to Jaguar Valley Drive, with many existing structures with shallow setbacks from the street, heritage properties, and congested traffic operations.

Preliminary design – pinch points 

As work for Mississauga East is advancing ahead of other areas along the Dundas BRT corridor, an additional evaluation process has been applied to the Cooksville pinch point to meet the requirements of the Investing In Canada Infrastructure Program (ICIP). All pinch points along the corridor will be assessed within the PDBC framework outlined below. 

The following slides document the feedback heard and the steps taken by the project team to design a preferred solution for the Dundas BRT corridor.  

During the last round of engagement, a pinch point was also identified in Toronto, on Dundas Street between The East Mall and Aukland Road. Technical work on this pinch point is ongoing and will be presented during the next round of engagement later this year. 

How are pinch points evaluated? 

In addition to the evaluation criteria identified as part of preliminary design, pinch point evaluation considers the technical categories below pertaining to the natural, cultural and built environment in each location. Following the first round of engagement, the below pinch point considerations were updated as a result of feedback provided by the public. Feedback provided identified environmental considerations as most important, followed by geometrics/infrastructure, traffic and property considerations and also contributed to additional evaluation criteria including capital cost, transit service reliability, cyclist and pedestrian accessibility and connectivity and road safety.

Mississauga East: key pinch point considerations

Key considerations for the Cooksville pinch point include:  

  • Existing narrow right-of-way (ROW) in many locations  
  • Property acquisition required to achieve the Official Plan ROW to accommodate all contemplated infrastructure needs (dedicated BRT guideway, four general purpose lanes, cycle tracks, sidewalks and amenity/utility space)  
  • Some buildings located close to the property/ ROW line  
  • Significant development intensification  
  • Hurontario LRT track and station stop  
  • Minimal natural heritage features  
  • Some cultural heritage resources  
  • Each design alternative has a varying impact on the community character of Cooksville Village, protecting or enhancing this area is a priority

During round 1 engagement, members of the public identified:

 

Opportunities to:

  • Implement the Dundas BRT Project as part of the City of Mississauga’s Dundas Connects Master Plan  
  • Implement a station stop to connect to the Hurontario LRT line  

Concerns about:  

  • Cycling infrastructure and safety  
  • Pedestrian infrastructure and safety  
  • Widening Dundas Street with additional lanes  
  • Landscaping (aesthetics)  

 

Short list of alternatives: Dundas Street in Mississauga – Cooksville pinch point 

Alternative 1: Full median BRT widened about the centreline (with two general purpose lanes in either direction). *

Alternative 3 – Full median BRT with no lefts at the Dundas and Hurontario intersection.  **

Alternative 4: Curbside busses in mixed traffic. **

Long list of alternatives: Dundas Street in Mississauga – Cooksville pinch point 

The following six alternatives were reviewed for potential benefits and drawbacks: 

Alternative 1: Full median BRT widened about centreline (with two general purpose lanes (GPL) in either direction) 

Benefits:

  • BRT operations and reliability  
  • Maintains continuity of median BRT and active transportation  
  • Provides acceptable auto travel times when compared to other alternatives  
  • Maintains BRT station at Hurontario with limited/no impacts to the Hurontario LRT  
  • Operates at capacity with acceptable auto travel times  
  • Will improve the overall community character of Cooksville Village through transit oriented development that a BRT will bring to the area  

Drawbacks:

  • Potential for heritage property and other property impacts and displacements  
  • Moderate capital cost to implement and purchase of properties 

 

Alternative 2:  Full median BRT (with one GPL in either direction) 

Benefits:

  • BRT operations and reliability  
  • Maintains continuity of median BRT and active transportation  
  • Potential to avoid displacing two heritage buildings with localized narrowing of the sidewalk and cycle track  
  • Minor potential impacts to existing and future land uses  
  • Will improve the overall community character of Cooksville Village through transit oriented development that a BRT will bring to the area  

Drawbacks:

  • Existing traffic operations fail through Cooksville. Queue lengths extend to Mavis and Cawthra  
  • Potential for one heritage structure and other property displacements  

Alternative 3: Full median BRT with no lefts at Hurontario 

Benefits:

  • BRT operations and reliability  
  • Maintains continuity of median BRT and active transportation  
  • Maintains BRT station at Hurontario with limited/ no impacts to the Hurontario LRT  
  • Will improve the overall community character of Cooksville Village through transit oriented development that a BRT will bring to the area  

 

Drawbacks:

  • Potential for heritage property and other property impacts and displacements  
  • Results in auto travel delays for westbound thru traffic, including increase queue lengths at Confederation Parkway

Alternative 4: Curbside buses in mixed traffic 

Benefits:

  • Maintains continuity of active transportation  
  • Avoids property impacts through Cooksville if active transportation is deferred to a later date  
  • Easiest and lowest cost to implement, compared to other alternatives  
  • Limited impacts to existing heritage properties and planned development  

Drawbacks:

  • Does not provide BRT continuity or active transportation (if active transportation is implemented later)  
  • Results in a two-minute reduction in BRT service through the area  
  • No continuity and less reliable than other alternatives  
  • Does not improve the overall community character of Cooksville Village through transit oriented development as no new transit infrastructure changes will be made to the area (beyond the Hurontario LRT)  

Alternative 5: Full median BRT with widening to the South 

Benefits:

  • BRT operations and reliability  
  • Maintains continuity of BRT and active transportation  
  • Operates at capacity with acceptable auto travel times  
  • Will improve the overall community character of Cooksville Village through transit oriented development that a BRT will bring to the area  

Drawbacks:

  • Extremely high capital cost due to property acquisitions required  
  • Redesign and construction of Hurontario LRT required  
  • Potential for one heritage property and other property impacts and displacements  

Alternative 6: Portal (BRT tunnel under Dundas Street)  

Benefits:

  • BRT operations and reliability  
  • Maintains existing Cooksville cross-section and community character  
  • Operates at capacity with acceptable auto travel times  
  • Property impacts could be mitigated through revisions to active transportation  
  • Will improve the overall community character of Cooksville Village through transit oriented development that a BRT will bring to the area, however, a below-grade alternative is less consistent with a transit oriented community  

Drawbacks:

  • Significant cost and construction implications  
  • Highest technical complexity and engineering design due to tunnel, utility relocations, and vertical access  
  • Profile of BRT below grade introduces 6% grades  
  • Traffic and Hurontario LRT service impacts during construction  
  • Potential for heritage and other property impacts and displacements  
  • Additional right-of-way and property impacts and displacements for utility relocations and underground station requirements, alternative vertical accesses, ventilation and pumping station(s)  
  • Potential impacts to Cooksville Creek  

Short list of alternatives: Dundas Street in Mississauga – Cooksville pinch point 

 

The best performing short list of alternatives was evaluated against the following criteria:  

 

  • Alignment with the 2041 Regional Transit Plan goals and objectives  
  • Alignment with the objective of the Dundas BRT to provide a high-quality regional transit corridor  
  • Transit customer experience  
  • Transit travel times  
  • Capital cost  
  • Environmental considerations  
  • Geometrics/infrastructure considerations  
  • Mobility and traffic considerations  
  • Property considerations 

Best performing alternative: Dundas Street in Mississauga – Cooksville pinch point

The evaluation of the short-list determined Alternative 1 – a full median BRT about centreline is currently the best performing alternative. Alternative 1 proved to be the best performing in terms of geometrics/infrastructure, mobility, traffic and property considerations. It would also provide a BRT station at Hurontario with limited to no impacts to the future Hurontario LRT line and would allow for optimal BRT operations and reliability.

Rendering: Typical bird’s eye view of Alternative 1 - Full median BRT widened about centreline.

The Environmental Project Report will identify potential impacts and appropriate mitigation measures associated with the chosen alternative.
