Signal installation means no trains will be running between Bloor-Yonge and St. Andrew stations from March 8 to 9.
You’ll have to make alternative travel plans if you were planning to ride the Yonge-University-Spadina line between Bloor-Yonge and St. Andrew stations in the next two days: trains on the University-Spadina line will be turning north again when they reach St. Andrew, and trains on the Yonge line will be doing so when they reach Bloor-Yonge.
There will be shuttle buses running between Bloor-Yonge and St. Andrew stations—and customers can also use the 6 Bay or 94 Wellesley buses, or the 506 Carlton, 505 Dundas, 501 Queen, and 504 King streetcars to fill the subway-line gap.
Why, you might ask, is the TTC insisting on shutting down the subway and creating such inconvenience for weekend travellers? The TTC is fully prepared to explain, and does so for a good seven minutes in this video outlining how signal systems work, why the TTC’s old one needs to be replaced, and why replacing it during localized subway shutdowns makes far more sense than doing so bit by bit in the middle of the night.
(And since the subway will be shut down anyway, the TTC will be taking this opportunity to continue construction work at Union Station—you’ll be able to use the PATH Network to get to St. Andrew Station.)
