The TTC has announced plans for construction projects that will require replacement of streetcars by buses on 510 Spadina starting June 23 until October 2024.

In June and July, overhead will be rebuilt between King and Queens Quay. This will not affect route 509 Harbourfront, and service on that route will be increased to offset the missing 510 Spadina cars on Queens Quay.

In August through October, overhead work will shift to the section from College to Spadina Station.

At Spadina Station, track will be replaced and other work will be done in preparation for a platform extension that will be enabled by excavation for a nearby condo.

There is no word on plans for the overhead between College and King, or whether another shutdown will be required for that segment.

Both the 510 daytime and 310 night buses will operate in mixed traffic stopping curbside along their route. Buses will use the surface loop at Spadina Station.
