Whilst walking along Somerset Street just west of the OTrain track, at Breezehill, I came across these gents taking bore-hole samples from the street. Little painted notations every few meters along the street indicate that they will be doing this for weeks.

I will nag the Somerset street planners for one bore hole result in particular. It will be the hole bored just a few meters east of the OTrain underpass. Eventually, a segregated bike route (CycloPiste de Preston?)  will be finished along the OTrain corridor, and to be useful it will likely have to pass under Somerset Street. Will it be possible to carve out a cycling tunnel along side the Otrain underpass?

If the viaduct (raised road surface that is Somerset Street) is composed of gravel and rock, it could be possible to pump that space just east of the Otrain underpass with grout (liquid cement) until it is solid, then carve out a bike route underpass parallel to the Otrain underpass. This would avoid digging up the road and building a cycling underpass in a cut and cover operation.
