The City of Toronto is defined and constrained by railways. The downtown is separated from the lake by the rail corridor, and another rail corridor slices through midtown. Between 1912 and 1915 a major grade separation project installed underpasses, including one here, on Dovercourt Avenue. A major electrical distribution corridor runs parallel to most of it; land under the corridor is used for parking, storage and occasionally a bit of parkland. It's ugly, disconnected and a great opportunity.
Earlier this year, Helena Grdadolnik of Workshop Architecture organized the Green Line ideas competition, to look at ways to tie it all together. There were in fact two competitions, A to develop an overall vision, and B, to look in detail at one of the underpasses.
