Preliminary Design – Design Progressed for Mississauga East

The Dundas Bus Rapid Transit (BRT) corridor outside constrained areas, or pinch points, in Mississauga East includes Etobicoke Creek to Jaguar Valley Drive. 

A detailed map outlining the route and highlighting the Erindale Valley pinch point and Cooksville pinch point.

Since the last round of engagement, the 10% Preliminary Design (PD) for this area has been further refined, based on feedback gathered from the public and stakeholders and additional technical studies undertaken by the Project Team. The outcomes of this design are: 

  • Right-of-way (ROW) widening up to 42m (from existing ROW of approximately 22 - 40m in the Cooksville pinch point, and approximately 36 - 40m outside of the pinch point), requiring property acquisition with potential impacts to landscaping, entrances and parking, buildings and structures.  
  • Corridor alignment optimized to minimize impacts to built and natural heritage features, as well as non-heritage properties.  
  • Corridor design optimized to minimize impacts to existing utilities, most notably the overhead hydro.  
  • Dedicated median BRT lanes to improve transit speed and reliability.  
  • Elimination of High Occupancy Vehicle lane and maintaining of two general purpose traffic lanes in each direction, with minimum widths (i.e., 3.35m through lanes) applied to eliminate or minimize property impacts.  
  • Enhanced active transportation, including dedicated protected cycling facilities.  
  • Enhanced public realm, where possible, with widened sidewalks, furniture (e.g., benches) and tree planning zones. Reductions in localized areas to eliminate or minimize property impacts, including a reduction in the furniture/pole zone (0.6m minimum) and sidewalks (1.5m minimum).  
  • Existing bridge and culvert replacements.  
  • Platform stop locations and geometry, including enhanced passenger protection with platform widths up to 4.2m where feasible.

Special Policy Area (SPA) Studies 

How are SPA studies different from the Transit Project Assessment Process (TPAP)? 

As the TPAP assesses the impacts and determines the proposed mitigation measures of the structure replacements proposed at Etobicoke Creek and Little Etobicoke Creek crossings, the SPA studies capture the proposed works for the watercourse channels and elsewhere within the floodplain.  

What’s happening now?  

Coordination with the following City of Mississauga SPA studies has progressed to ensure that the Etobicoke Creek and Little Etobicoke Creek crossings are coordinated to meet the goals and objectives of both the Dundas Bus Rapid Transit (BRT) and SPA studies:  

  • Dixie-Dundas Flood Mitigation EA Study (Little Etobicoke Creek SPA)  
    • A short-list of conceptual culvert replacement options has been developed.  
    • Preliminary Design to be developed for spring 2022.  
  • Etobicoke Creek SPA Feasibility Study  
    • Hydraulic Analysis completed.  
    • Confirmation that existing structure has sufficient hydraulic capacity.  

Dundas Street will be widened in certain areas to accommodate the proposed Bus Rapid Transit (BRT) lanes and facilities, including four general purpose traffic lanes, cycling facilities, wider sidewalks (where possible), and amenity space for utility poles, trees and street furniture. The Preliminary Design, as shown in the cross sections and roll plans, has been updated since the last round of engagement to reflect these design refinements. 

Two illustrations of what Dundas Street could look like with the implementation of the Dundas Bus Rapid Transit (BRT), including lane widths, active transportation paths, dedicated transit lanes, and roadways. The first alternative, Typical Cross Section at Dixie Road, includes a dedicated bus platform. The second alternative, Typical Cross Section at Midblock Jaguar Valley Drive to Etobicoke Creek, includes raised medians and two-way transit lanes.
