MassDOT will make minor adjustments to the congestion relief trial at the I-90/I-95 interchange in Weston. The adjustments will be made tonight, Monday night July 29, into Tuesday morning July 30, weather permitting.  The changes are based on staff observations and feedback from customers. MassDOT will install better signage and reposition the location on the lane closure slightly farther south on I-95 Northbound, closer to Exit 23-24-25.

In an effort to develop low-cost bottleneck solutions, MassDOT consulted both the Federal Highway Administration and the Boston Metropolitan Planning Organization. Analysis confirmed the primary sources of congestion at the I-90/I-95 interchange in Weston are the multiple merge points. The bottleneck builds as traffic from I-90 and Route 30 merges onto I-95 Northbound. To address this bottleneck, MassDOT will be closing the right lane on I-95 Northbound through a temporary tapered lane closure, just north of the I-95 NB Exit 23-24-25.

Currently, I-95 NB is four lanes wide with the right-most lane carrying thru traffic and vehicles that are merging onto I-95 NB from the Mass Pike and Route 30. This double-merge point causes traffic to back up through the Toll Plaza and onto I-90.

By closing the right lane to I-95 NB travelers, it becomes a dedicated lane for MassPike/Route 30 travelers to merge onto I-95 NB.

A third of all traffic on I-95 NB exits at Exit 23-24-25, and a recent traffic count showed 10 percent of vehicles continuing north on I-95 utilize the right lane. During the trial period, thru traffic on I-95 Northbound should stay to the left. Hesitation is common around new traffic patterns and public awareness will be key.

The trial began on July 17th and has been extended to August 9. During the test, MassDOT will collect information to ensure that the new configuration reduces congestion levels as predicted. If the trial period proves successful, MassDOT will make the changes permanent by installing new signs and new lane markings later this summer.
