The downtown eLRT line could be extended from Bayview to Tunney's Pasture along the transitway.

The eLRT would share the transitway with buses coming in from the west. Some bus routes (16,18,55,57,86,176) would terminate at Tunney's rather than continue to Bayview. These routes would extend North into Tunney's Pasture providing a circulator service for people getting off the LRT or other buses.

Other routes would continue to terminate at the Bayview transfer station.

This extension would reduce the number of transfers for East end originating employees of Health Canada and Stats Canada.

The LRT heading West from Bayview would climb a ramp on the North side of the transitway trench between Parkdale and Holland Avenue and stop at grade on the East site of Holland. This would allow trains that reverse here to do so without interfering with buses travelling in the transitway trench below.

A huge advantage of this for passengers is that they will not have to climb the stairs to get to the buildings at Tunney's. Employees who work in some of the further buildings may prefer to take one the bus routes (16,18,55,57,86,176)
that terminate at Tunney's, but which would circulate through the campus first. This would definitely be nice on wet or snowy days.

This extension could be done for less than $29M.

(note that the rock cut required to climb out the trench is actually less expensive than the equivalent amount of shared bus/rail roadbed)
