I'm glad they didn't go with Figure 4-9, as that would be inappropriate for a corridor with such low bus service demand. I'm hoping, but not optimistic, that the "protected bike lane" is actually protected, by at least bollards.
I hope we can see robust bus infrastructure on the stretch of Columbia Rd where there is actual demand for such infrastructure, between Blue Hill Ave and JFK/UMass, but I'm not holding my breath.
