MassDOT will be reducing the number of lanes on I-90 (Massachusetts Turnpike) through Boston and closing the BU Bridge and sections of Commonwealth Avenue to all traffic between July 27th and August 14th. The closures are necessary for reconstruction of the bridge that carries Commonwealth Avenue and the MBTA Green Line over I-90 (Massachusetts Turnpike).
Significant traffic disruptions are expected during the 18-day construction period on the following roadways:
The road closures and bridge reconstruction will also impact transit service. The MBTA Green Line Boston College “B” branch will be replaced with buses between Packard’s Corner and Kenmore Square. Inbound trips to downtown Boston will require passengers on the ‘B” branch to transfer from a train to a bus at Babcock Street station and then from the bus back to a train at Blandford Street Station.
MBTA Bus Routes 47 & CT2 will operate across the BU bridge during construction but all buses will detour onto St. Mary's Street around the project limits.
MBTA commuter rail will operate on normal schedules during the week but will be unavailable during the weekends of July 29-30th and August 5-6th.
Traffic and transit disruptions will significantly impact travel between the Longwood Area and the following areas:
Access for emergency vehicles, local abutters, pedestrians and bicycles will be maintained through the construction project during the traffic closures.
This page provides updates on the construction project and information on alternative transportation options for employees, students, patients, and visitors to the Longwood Area. For additional help, please contact the MASCO CommuteWorks Coordinator.

I-90 (Massachusetts Turnpike) lane restrictions start July 7th
On July 7th I-90 (Massachusetts Turnpike) will be reduced to 3 lanes in each direction between the Allston Interchange and the Beacon Street Overpass in Boston and will remain in this configuration after the shutdown until August 28th. The lane closures are needed so that MassDOT can prepare for the major construction activities for the 2017 Construction Shutdown starting on July 16th.
Pre-construction public meetings
MassDOT will also be hosting two pre-construction public meetings:
Tuesday, July 11, 6:30 PM
Boston University College of General Studies
Jacob Sleeper Auditorium (Lower Level, Room 129)
871 Commonwealth Avenue, Boston
Thursday, July 13, 6:30 PM
Newton Free Library, Druker Auditorium
330 Homer Street, Newton
Everyone is encouraged to help reduce travel through the area during the 18-day construction period. Please consider the following options:
Work from home: employees in the Longwood Area should explore their options for working from home during the closures. Better yet, take advantage of the summer weather to schedule a vacation!
Try Public Transportation: services like the MBTA Commuter Rail, the Orange Line from Wellington, and the Green Line from Riverside or Lechmere are great alternatives to sitting in traffic.
Try Walking or Bicycling: build some exercise into your travel to and from the Longwood Area. Many institutions in the Longwood Area have showers and locker rooms available to make these options easier for you during the hot summer months.
Change Your Work Schedule: does your employer allow you to work flexible hours or a compressed work week? If so, it may be easier for you to switch your commuting hours and avoid the added traffic during the bridge reconstruction.
Form a Carpool: create a profile on NuRide to find other area employees who wish to carpool.
Seek Alternate Driving Routes: travel conditions on I-90 (Massachusetts Turnpike), Soldiers Field Road, Storrow Drive, Memorial Drive, Park Drive, Massachusetts Avenue, Beacon Street, Cambridge Street and Harvard Avenue/Harvard Street will be congested during the bridge reconstruction. Please avoid travel on these streets as much as possible.
