Phase 2 of the planned reconstruction of sewers and track on College and Carlton requires 506/306 streetcars to divert via Dundas Street between Bay and Parliament Streets. A replacement bus service will operate on College and Carlton. This arrangement begins on July 26 and is expected to continue until the end of 2026.

506B/306B buses will run from Spadina Station to Broadview & Gerrard:

• Eastbound via Spadina, College, Carlton, Parliament and Gerrard looping near Bridgepoint Hospital.
• Westbound via Gerrard, Parliament, Carlton, Jarvis, Wellesley, Bay, College and Spadina

Note that there will be no westbound service on Carlton/College between Jarvis and Bay because the street will be closed in that direction in the work zone. One eastbound lane will remain open.

This phase of the work includes:

• Reconstruction of the sewer and watermain on College between Bay and Yonge, and
• Reconstruction of the streetcar track on Carlton between Yonge and Church.

In Phase 3 later this year, the work zones will switch with streetcar track replacement west of Yonge.

As with the King Street project described in a separate post, it should be noted that the work by Toronto Water is the lengthier of the two components. As the City upgrades water and sewer infrastructure that is over a century old, there have been many disruptions to streetcar routes, although track and overhead upgrades are scheduled concurrently to take advantage of the streetcar diversions.
