Proposed Infrastructure

Stouffville Rail Corridor Grade Separations - Proposed Infrastructure - Public Information Centre #2

To support the GO Expansion Program,  the Stouffville Rail Corridor Grade Separations Project is proposing seven (7) grade separations or road closures along the Stouffville rail line.

Purpose and benefits of grade separations

A grade separation separates the road from the rails, so that vehicles and or pedestrians can pass under or over a railway, without having to stop and wait for the trains.

Grade separations are essential to support transit expansion, and provide other community benefits, including:

  • Improved traffic flow and elimination of the potential for conflicts between trains and vehicles
  • Better connections and crossings for pedestrians and cyclists
  • Air quality benefits from reduced car idling
  • Reduced noise from at-grade crossing signals and train whistles
  • Opportunities to bring roads up to new standards, by incorporating wider lanes and sidewalks, separated bike lanes, or improved lighting

Metrolinx is improving service as part of the GO Expansion Program by increasing train frequency and availability. The long-term goal and vision of the GO Expansion Program is to provide 15-minute two-way all-day service.

With trains planned to run every 15 minutes (a crossing every 7 minutes in one direction or the other), it is not possible to maintain at-grade crossings.

By grade separating the crossings, Metrolinx can increase travel speed and capacity on our rail lines by allowing trains to freely pass over or under roads without the need for stoppages. Grade separations will support the growth of our cities by increasing traffic flow and transit capacity.

Proposed grade separations

The Project includes the following seven proposed grade separations and road closure:

City of Markham, York Region

  • Denison Street, Road Under Rail Grade Separation
  • Kennedy Road, Road Under Rail Grade Separation

City of Toronto

  • Passmore Avenue, Road Under Rail Grade Separation
  • McNicoll Avenue, Road Under Rail Grade Separation
  • Huntingwood Drive, Road Under Rail Grade Separation
  • Havendale Road, Road Closure with Multi-use Crossing
  • Progress Avenue, Road Over Rail Grade Separation
