Harvard Street changes from a two lane sans bike lane to a single lane with bike lane at the corner of Longwood Ave. Motorists in the southbound lane ignore the sharply narrowing roadway, using the bike lane as an egress to the bottleneck. Cyclists attempting to enter this lane from the shared southbound lane are pinned to the curb and frequently hit. I was hit today, and have been hit in the past by unwary and aggressive motorists. Please redesign this roadway before someone is killed.
