The TTC will be rebuilding the track at the intersections of King & Charlotte and Adelaide & Charlotte beginning on March 29. Charlotte Street forms the eastern part of the loop used by 510 Spadina cars at King Street.
For the period from March 29 to April 10 while King & Charlotte is under construction:
- 504 King streetcars will divert eastbound via Spadina, Queen and Church, while westbound service will divert via York, Queen and Spadina.
- 510 Spadina streetcars will all operate at least to Queens Quay loop.
- A 504 shuttle bus service will operate between Strachan and Church diverting around the construction via Richmond westbound and Front eastbound.
For the period from April 11 to 26 while Adelaide & Charlotte is under construction services will operate on their normal routes, although 510 Spadina cars will continue to operate to Queens Quay rather than turning at Adelaide.
