Weekend and nightly closure: The Longfellow Bridge will be closed to all motor vehicle traffic from 11 PM on Friday 7/29 to 5 AM on Monday 8/1. Bike and pedestrian access will be maintained, and there is no impact to Red Line service. This same closure (11 PM to 5 AM, motor vehicles only) will occur each night next week as well (Mon-Fri).
Traffic Shift: Following the rearrangement of Red Line tracks earlier this month, another major milestone is about to occur, this time for vehicular traffic. Starting Monday 8/1, all motor vehicles will shift to the upstream (normally Boston-bound) side of the bridge. This will mark the first time drivers will be using a rebuilt section of the bridge. There are no changes to the overall detour plan (all traffic will be Cambridge-to-Boston only), but the crossover on the Cambridge side will no longer be needed. Please watch traffic patterns carefully when using the bridge next week!
