The Richmond lights are a good thing, but lights at Simcoe/Queen and Simcoe/Dundas as well would essentially extend the Simcoe St. bike lanes to College (with a few jogs north of Dundas)
I live at Simcoe/Dundas, so go north on Simcoe frequently, but never liked Queen there. Technically the lane ends there, and paint markings indicate bikes should turn right only. However, I usually wait for a gap to cross north to cut through that closed off section between the insurance buildings. As for lights, I definitely think Richmond needs it, but not sure about Queen because of that closed off road. As for Dundas, I personally think St Patrick is a better stop for lights due to northbound traffic trying to get onto Dundas plus the curve there causes many close calls between impatient motorists and pedestrians alike.
