commave_msthdBeginning at 9:00 PM on Friday, June 1, MassDOT will reduce I-90 between the Allston Interchange and the Beacon Street Overpass in Boston to two lanes in each direction. I-90 will reopen to four lanes in each direction by 5:00 AM on Sunday, June 3.

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 2018 Construction Shutdown (July 26 – August 11), with the goal of making sure it will run as smoothly as possible.

The I-90 Eastbound on-ramp from Cambridge Street/Soldier’s Field Road will be closed during the dry run. The I-90 Westbound Exit 20 off-ramp to Brighton/Cambridge will be closed intermittently. See the I-90 (Mass Pike) Ramp Closures Detour Map and directions on the Traffic Management page.

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 local vehicular traffic during the dry run.

I-90 Impacts during the 2018 Construction Shutdown

From 9:00 PM on July 27 to 5:00 AM on August 6, MassDOT will implement lane reductions and ramp closures on I-90 in Boston (between the Allston Interchange and the Beacon Street Overpass), as follows:

  • Two lanes in each direction during peak hours (additional lane closures during weekends and off-peak hours).
  • The I-90 Eastbound on-ramp from Cambridge Street/Soldiers Field Road will be closed this entire period.
  • The I-90 Westbound Exit 20 off-ramp to Brighton/Cambridge will be closed intermittently.
  • The lane reductions will be necessary during the shutdown for the contractor to access the Commonwealth Avenue Bridge for demolition and replacement (see the video simulation of the project on YouTube).

For a full list of traffic impacts during the 2018 Construction Shutdown, see the Traffic Management page of the project website.

Please share this advisory with anyone you think may be interested in the project, and encourage them to sign up for email alerts for traffic updates and meeting announcements.
