Lane Reductions on I-90 (Mass Pike) on the Weekend of June 3-4 for "Dry Run"
From 11:59 PM on Friday, June 2, to 5:00 AM on Monday, June 5, MassDOT will reduce I-90 (Mass Pike) between the Allston Interchange and the Beacon Street Overpass in Boston to 2 lanes in each direction. The I-90 Eastbound on-ramp from Cambridge Street and the I-90 Westbound Exit 20 off-ramp to Brighton/Cambridge will also be closed intermittently (see the I-90 (Mass Pike) Ramp Closures Detour Map).
This will allow MassDOT and its contractor to conduct necessary preparation activities and a “dry run” to test the I-90 traffic logistics for the 2017 Construction Shutdown (July 26 – August 14), with the goal of making sure it will run as smoothly as possible.
During the dry run, a “crossover” on I-90 will direct all vehicles to either the eastbound or westbound roadways at different periods of time. There will be no impacts to the MBTA Green Line, Commuter Rail, or Commonwealth Avenue during the dry run.
Important Information on Travel Disruptions between July 26th and August 14th 2017
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 Cambridge-bound service will detour through Kenmore Square.
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.
