Starting Monday, January 26, the TTC will detour southbound buses operating along Bathurst Street. Northbound buses operate along their regular routes.

7B Bathurst
310 Bathurst (overnight)

Buses operate along their regular route to Bathurst Street and Davenport Road, then detour:

westward along Davenport;
southward along Christie Street; and then
eastward along Dupont Street to Bathurst,
resuming their regular route southward along Bathurst.

This work is the last phase of the ongoing City and TTC project to upgrade Bathurst Street between St. Clair Avenue West and Bloor Street West and renovate the streetcar tracks along Bathurst Street and Vaughan Road. The project started on May 20, 2008 and continued through various diversions and phases on May 23, June 2, July 3, July 14 and July 25. Service returned to Bathurst Street on August 30, 2008.

The TTC has split the 7 Bathurst route into two parts since March 30, 2008, as a result of various construction projects on Bathurst Street and St. Clair Avenue West and at St. Clair West Station.

The City, TTC and CP will complete this phase of the project in three stages:

• Stage 1 (From January 19 until about March 22) involves lowering the roadway, upgrading utilities and replacing streetcar tracks on the west side of Bathurst Street. During Stage 1, the City will maintain one lane of northbound traffic and permit pedestrians access to the east sidewalk at all times. During Stages 1 and 2, the City will reroute southbound traffic at Davenport Road to detour around the work zone. The City will maintain local traffic only south of Davenport Road.
• Stage 2 (From about March 23 until about May 30) involves lowering the roadway, upgrading utilities and replacing streetcar tracks on the east side of Bathurst Street. During Stage 2, the City will maintain one lane of northbound traffic and permit pedestrians access to the west sidewalk at all times.
• Stage 3 (From about May 31 until about August 30) involves rehabilitating the east part of the bridge. The work includes new sidewalk, railings and new pedestrian and vehicular lighting. During Stage 3, the City will maintain one lane of traffic in each direction on the west side of Bathurst Street. Pedestrians will have access to the west sidewalks.
• Stage 4 (From about August 31 until about January 31, 2010) involves rehabilitating the west portion of the bridge. The work includes new sidewalk, railings and new pedestrian and vehicular lighting. During Stage 4, the City will maintain one lane of traffic in each direction on the east side of Bathurst Street. Pedestrians will have access to the east sidewalks.
