Somerville Traffic Pattern Changes on McGrath Highway Take Effect Monday, April 11


Somerville Ave. off-ramp to close permanently. Traffic pattern change at Somerville Ave. to Medford St. and Rt. 28 goes into effect as of 10 a.m. on April 11.
SOMERVILLE – IMPORTANT TRAFFIC PATTERN CHANGE! Beginning on Mon., April 11 (weather permitting), the Massachusetts Department of Transportation (MassDOT) will permanently close the off-ramp from McGrath Highway southbound to Somerville Ave., and will open a new at-grade, signalized connection from Somerville Ave./Medford St. to McGrath Highway northbound. The existing tunnel from Somerville Ave. to Washington St. will be permanently closed (see attached photo).
Traffic will be rerouted as follows:
McGrath Highway southbound to Somerville Ave.: Vehicles will be rerouted to the Washington St. off-ramp to Medford St. (NOTE: the Washington St. exit is BEFORE the Somerville Ave. exit. Please follow signage.)

Medford St. and Somerville Ave. northbound: Vehicles will follow a new traffic pattern and new traffic signal/connection at the Somerville Ave. /Medford St. intersection.

This work is an interim improvement phase of the long term McGrath Boulevard Project. When fully complete in the summer of 2016, this interim measure will provide increased pedestrian and bicycle access at both the Washington St. and Somerville Ave. intersections with McGrath Highway Traffic signal upgrades will be made at Somerville Ave.
