This past summer MassDOT implemented a right lane closure on I-95 Northbound, just south of the I-90 (Mass Pike) on-ramp. After an evaluation of the traffic volumes northbound on I-95, it is determined that a three lane section, between the I-95 exit (Exits 23, 24, 25) to the Mass Pike and the I-90 on ramp to I-95 Northbound has adequate capacity during the A.M. and P.M. peak hours to handle the traffic volumes.

MassDOT implemented the aforementioned right lane closure on I-95 Northbound in order to mitigate traffic from I-90, Rte. 30 and Recreation Road trying to access I-95 North.

As a result of the study, MassDOT determined traffic delays on I-95 Northbound resulted in an additional 50 seconds of travel time between the Rte. 9 interchange and Rte. 20 interchange. Delays on I-95 Northbound south of Rte. 9 were not considered as part of the study area. Delays south of this point are impacted by ever-changing, unpredictable factors such as: breakdowns, police activity, and slow moving vehicles which compound delays.

The study also determined that delays decreased by 18.6 minutes from the Weston State Police Barracks to Rte. 20. This is a dramatic reduction in travel time for an Interstate highway and achieves MassDOT’s original project goal of delivering to our customers a low-cost, effective congestion reduction measure.  Please read the full statement on the permanent change.
