The TTC has announced the timing of various projects affecting the 501 Queen route through the 2017 construction season.

Previously announced work includes:

Reconstruction of The Queensway from Parkside to Humber Loop including the bridge deck at the Humber River

Reconstruction of Humber Loop and installation of a new substation to improve power on Lake Shore west of the loop

Reconstruction of track on Lake Shore to Symons Road (surface layer only) to replace rail prematurely corroded by electrolysis

Reconstruction of track on Lake Shore from Symons to Dwight (full reconstruction)

Toronto Water construction from Spadina to Bathurst

Replacement of the pedestrian bridge west of Yonge over Queen

Starting on Sunday, May 7, route 501 will be operated by buses with a structure similar to the streetcar service before it was split at Humber Loop. The turnback point for half of the service will be Park Lawn. This arrangement will be in place until Sunday, September 3 when streetcars will return to the central portion of the route.

Streetcars displaced from 501 Queen will be used on 511 Bathurst, 504 King (trippers) and 503 Kingston Road Tripper. 502 Downtowner will remain a bus operation.

Additional work is planned through the year that cannot be scheduled concurrently with City activities over the summer, and this will trigger other diversions and bus shuttles later in the year.

Toronto Water work on Coxwell will affect the intersection at Queen, and the 503 Kingston Road Tripper will revert to bus operation in August.

Track replacement at Coxwell will occur in September. Although streetcars will return to 501 Queen, they will only operate between Connaught Avenue (Russell Carhouse) and Roncesvalles. Shuttle buses will operate from Neville to Carlaw, and from Roncesvalles to Long Branch. It is unclear whether this actually means a return to shuttles as far east as Dufferin, or if the TTC plans some other scheme for the eastern terminal of the “501L” service. This arrangement will remain in place until October 14. Streetcar service to Neville will resume on October 15.

Track replacement at McCaul will occur in October/November, and this will require the familiar Church, King, Spadina diversion of all 501 cars around the site. Shuttle buses will operate between the Church and Spadina via Queen. This schedule will be in place until November 25, although if past history is repeated, the streetcars may come back to Queen once the work at McCaul is completed and the concrete has time to cure.

Streetcar service beyond Roncesvalles will not resume until the end of 2017.
