Several projects sprang up with the warm weather in Toronto, and more are to come.

Updated May 13, 2016: Details of diversions and replacement services for College Street projects have been added to the end of this article.

Updated May 13, 2016 at 3:00 pm: Details of diversions and replacements updated for 506 Carlton and 512 St. Clair.

First off was the replacement of special work on Charlotte Street at Adelaide and at King including removal of the never-used lead to Adelaide Street eastbound.

Next was the replacement of the southwest ladder track at Roncesvalles Carhouse. Because of the odd shape of the property, this carhouse has many interesting twists and turns in its layout.

A short section of Bay Street south from Elm has been in rough shape with a slow order for a few years. Now the track has been replaced.

Pending work for the construction season includes:

Richmond Street tangent track from east of Yonge to York. This is part of an overall reconstruction of the street previously begun by Toronto Water.

College at Bathurst (June 20 to July 22) and at Lansdowne (July 11 to 22). This is part of a set of projects affecting College Street described in detail on the City’s website. See below for details of service diversions and bus replacements.

A shutdown of 512 St. Clair will be required for the reconstruction at both St. Clair West and St. Clair Stations. This will begin concurrently with the reconstruction of Bathurst & College.

As of May 9, the 501 Queen service is diverting around Toronto Water construction via Spadina, King and Shaw. This will be in place until Thanksgiving weekend unless the work is finished early.

Diversions for College Street Projects (Added May 13, 2016)

Illustrations here are taken from display panels for a public meeting earlier this year.

Through the summer to the Labour Day weekend, the 506 Carlton route will operate with streetcars on the eastern portion of the route looping downtown via Bay, Dundas and McCaul. This route stays the same throughout the period because it is not affected by construction projects further west.

The western end of the route will operate with buses whose location will vary from phase-to-phase of the work. The service will loop east of Yonge Street via Jarvis, Maitland and Church. Note that the section between Dufferin and Lansdowne will be affected by construction work that will take place for some or all of the summer (see later maps below).

Updated May 13 at 3:00 pm: The split service shown below will operate on weekdays. On weekends, buses will provide service over the entire route diverting as necessary between Spadina and Lansdowne.

While College and Bathurst is under construction, services will be modified as shown below.

The 506 west bus will divert via Spadina, Harbord and Ossington. The 511 Bathurst car will be replaced with buses diverting via Dundas, Spadina and Harbord.

During a considerable portion of the project, water main work between Dufferin and Lansdowne will require the 506 west bus to divert via Dufferin and Dundas.

While the intersection of College and Lansdowne is under construction, the 47 Lansdowne bus will divert via Dufferin Street from Bloor to Queen southbound, and will operate northbound via Lansdowne only to Dundas Street, then via Dundas and Dufferin to Bloor.

Updated May 13 at 3:00 pm: 512 St. Clair will be converted to bus operation during construction work at St. Clair West and St. Clair Stations throughout the summer. Buses will serve St. Clair West at on-street stops. During the September-October schedule period, construction work at St. Clair Station will require bus operation from St. Clair West Station to St. Clair Station.
