1. Leaving Exhibition Station, the line runs east at surface level, under the bridge at Strachan Avenue.
2. Launch shafts and portals will be constructed at the site of the future Ordnance Park on the north side of the existing GO Corridor for the beginning of the Ontario Line tunnels. From here, the tunnel boring machines will begin to work their way east and then turn north.
In the short term, the future park site will be needed to support tunnel construction. After construction is finished, an opportunity to create a new park above the tunnel will be available for City of Toronto programming, in keeping with their existing plans for the site.
3. Plans are to preserve Garrison Crossing, the pedestrian bridge that spans the rail corridors in the area and connects with the future park site. While there may be times when it will be closed due to construction work, Metrolinx is studying ways to minimize impacts and maintain pedestrian and cycling access across the rail corridors for the duration of the project.
Tunnel work is anticipated to begin after financial close is reached for the Southern Civil, Stations and Tunnel procurement package.
