The Town of Brookline is evaluating a proposal to dedicate new bus lanes on a short but congested section of Washington Street between Brookline Village and the Riverway near the Boston city line. Brookline’s proposed Washington Street bus lanes, highlighted on a map of bus delays on the MBTA’s highest-ridership bus routes. Washington Street has recently been completely rebuilt as part of the town’s “Gateway East” project, which has been under construction for a year and a half. The project (pictured above, in December) rebuilt the street and sidewalks, realigned intersections, and added new protected bike lanes that give bike riders a safe connection between Brookline Village and the Emerald Necklace bike paths.
