From the 401 south to Eglinton, the roadway was to be in a trench, with the rapid-transit line in the middle. South of Eglinton, it continued into the Cedarvale Park below ground level. The route south of Eglinton was never built and several variations of the plan were proposed. Plans were initially for the road to be on the surface of the ravines and the subway below the surface, at least as far as Spadina Road with a tunnel under St. Michael's College north of St. Clair. Another plan projected the roadway to be completely underground also for this stretch, on top of the subway line. From Spadina Road south of St. Clair and further south, the roadway would be underground to Davenport Road, opening into an interchange on Davenport Road.
