We anticipate high volumes of pedestrians and bicyclists within those areas that would result in too many conflicts for bicyclists to safely ride. There will be portions of the route near the work zone where cyclists will have to walk their bikes due to limited width in those areas that must be shared with pedestrians.There are no crossings between Amory St and Carlton St.Eastbound bicyclists will continue to use the existing westbound bicycle lanes.They will cross back to Comm Ave westbound at Amory St. Westbound bicyclists will cross at Carlton St and continue westbound in a temporary bike lane alongside the bus-only lane in the eastbound roadway.Eastbound bicyclists heading to the BU Bridge will cross Comm Ave at Carlton St to a shared bike/pedestrian walkway to travel westbound to connect to the BU Bridge.Mary's St as an alternative to north-south bike travel between the BU Bridge and Mountfort St/Essex St. Bicyclists will be routed to Amory St and St.
