So there has been a lot of talk about how to upgrade the SRT, but there has been very little talk about what to do during the 4 years that the SRT is going to be shut down. I put some thought into it, and I came up with a low-cost way to keep the replacement buses actually moving while construction is underway.
What I came up with is the idea of a Scaborough Busway, running primarily through the hydro corridor. The corridor has 3 distinct segments:
1) Mixed traffic from STC to the hydro corridor, with maybe some queue jump lanes at major intersections. Widening McCowan would be too expensive.
2) Hydro corridor BRT with a dedicated roadway. Far side stops at all major intersections, with the station areas being 4 lanes to allow for passing.
3) Hydro corridor BRT through the narrow hydro ROW leading down to Kennedy Station.
What I envision is a couple different bus routes using this Busway to reach Kennedy. I also envision an express bus from STC to Kennedy, with few to no stops in between. There can be 5 or 6 bus routes throughout Scarborough that can be rerouted to use this Busway, especially the ones that used to dump passengers off onto the SRT.
I have also included a possible eastward extension to Morningside, using the hydro corridor. I have also shown mixed traffic branches to Malvern and to UTSC. This extension would allow the Busway to still have a usefulness even after the SLRT is in operation.
I think that this solution is the best way to avoid total bus gridlock while the SRT is shut down.
