The tunnel originally ended immediately north of the station at Summerhill Avenue and continued in open cut as far as Pleasant Boulevard, just before St. Clair, the next station.
Various sections of this open cut were roofed over as the years passed, and since the early 1980s it has been entirely under cover, except when one block was opened to allow new construction above it.
Passengers who look out from the train into the tunnel on this section can still see the sloping sides of the original cut, the stumps of lamp posts and trees, and the undersides of four bridges which still carry side streets over the line.

South of the station, the tunnel emerges to the surface at Rowanwood Drive.
Originally the line surfaced at Price Portal, but a one-block section from Rowanwood Drive to Price Street was roofed over in 2002 for parking.
