Workers on Tuesday will begin putting down stripes on Charles River Dam Road in preparation for bus-only lanes for the buses that will replace the Green Line between North Station and Lechmere for a year while parts of the current Lechmere Viaduct is torn down and then moved as part of the Green Line Extension into Somerville.
Beginning Sunday, May 24, Charles River Dam Road will include all-day, bus-only lanes in both directions. In addition to MBTA buses, professionally driven coaches, shuttle buses, and emergency vehicles will be allowed to fully access the bus lanes. Dedicated bicycle lanes installed on Charles River Dam Road last year will remain in place and fully operational for the duration of the bus replacement service. In addition to preserving the existing bicycle and pedestrian accommodations, the design will maintain three vehicular travel lanes: one in the Boston-bound direction and two in the direction of Cambridge.
