You're not? Could have fooled me, the drawing is spot-on! In fact I don't see a single drawing or pavement marking error, which is a feat some professional planners and engineers don't even achieve when submitting drawings for review!
My main thought is that the portal should be further south for a couple reasons:
- The subway alignments under the bridge are close to the edges (under the curb lane if I recall correctly). In your picture the northbound track would need to do quite an abrupt turn underground to line up.
- Moving the portal frees up space on the northbound approach of the intersection. This could be used to either shrink the size of the intersection east-west, or to provide a second northbound right turn lane (which would allow the east half of the crossing to get a walk like sooner, giving them a head start westbound while cars are still turning left on the west side).
Also, why did you provide a westbound left-turn bus lane? Wouldn't the bus be replaced by the streetcar? Eliminating that lane would free up space to provide a more substantial buffer on the bike lane along the bridge.
This is for the Wellesley Bus, not Parliament (which would be replaced by the streetcar)
