Three major construction projects will affect the 511 Bathurst route through 2020:

Reconstruction of the bridge over the rail corridor south of Front Street.

Track replacement on Bathurst from south of Dundas Street to north of Wolseley Loop.

Track replacement at Bathurst Station Loop.

Beginning April 20, buses will replace streetcars on Bathurst for the remainder of the year. At the south end of the route, because of the configuration of the intersection at Lake Shore/Fleet and Bathurst, the buses will divert via Fort York Boulevard as shown in the TTC notice below.

For the track replacement between Dundas and Wolseley Loop, welding of rail into strings was supposed to begin soon, but this has been postponed (as has similar work on Howard Park east of High Park Loop). The construction periods for these projects have not yet been announced.

At Bathurst Station, track replacement on Bathurst Street and inside the station itself is planned to occur between June 21 and September 5. During this work, routes 511 Bathurst and 7 Bathurst Bus will divert to Spadina Station. Arrangements for the 307 Bathurst Night Bus have not been announced.
