Lechmere station is a light rail station in Lechmere Square in East Cambridge, Massachusetts, near the intersection of Cambridge Street and Monsignor O'Brien Highway (Route 28). An elevated station is under construction nearby as part of the Green Line Extension, replacing the former surface-level station, which closed on May 24, 2020. The bus terminal at the old station remains open as a transfer point between MBTA bus routes and Lechmere– shuttle buses until the new station opens. The new station will be served by the D branch and E branch of the MBTA Green Line upon its planned October 2021 opening.
