Scarborough RT Express Bus Replacement Plan

After extensive study and public consultation, TTC staff will present a plan for bus replacement of the Scarborough RT to their Board at its April 14, 2022 meeting. Although it is a long report, much of it has appeared before during the consultative process and in an interim report to the Board. Interested readers can browse the full version, and I will only touch on the major points here.

My apologies for the resolution on some of the drawings included here. The versions in the TTC report online are not good, but if better renditions show up in the future, I will replace the originals here.

The Scarborough RT is on its last legs and, frankly, should have been replaced years ago. Let us not get into the whole subway/LRT debate as that train has left the station. However, the constant delay in making any decision has now pushed the opening of any replacement service well beyond the reasonable lifetime of the existing SRT fleet, and even that will require work to keep it operating until bus facilities are ready.

Various dates for the SRT shutdown are proposed, and these depend on completion of alternate bus terminal facilities. Thanksgiving weekend would certainly be an ironic cutover date.

The candidate dates for Q4 2023 would mean the last day of train service could be: Saturday October 14, 2023; or, Saturday November 25, 2023. If construction is complete ahead of schedule, a September closure date could also be possible, on Saturday September 2, 2023.

The Recommended Option

When the need to close the SRT before the Scarborough Subway Extension opened became apparent, the first thought was that riders would be consigned to buses plying the roads from Scarborough Town Centre to Kennedy Station for many years.

To no great surprise, there was a better idea that emerged during the consultations: use as much of the existing SRT right-of-way as possible for a bus roadway bypassing local street and intersection congestion and providing a direct access to Kennedy Station. That is the scheme that has been recommended, named in the report “Option 1 Hybrid Line 3 ROW” (Right-of-way).

As shown in the map below, the bus service will operate from STC station to Kennedy on street to Ellesmere Station and then on a new road in the existing SRT right-of-way to Kennedy Station. Stops will roughly match the existing SRT, except for McCowan. A new stop will be added at Tara Avenue, ironically a proposed station location decades ago when the SRT was to be built as a conventional LRT line.

The frequency of service is such that aggressive transit priority measures will be needed for the on-street portion.
