Somerville Green Line Extension Update: School St. Bridge Closure Extended Through at Least April 12

The School St. bridge closure currently in effect will be extended through at least April 12 to advance Green Line Extension (GLX) construction. Extending the current closure during this period of minimal traffic is intended to accelerate productivity and minimize the cumulative impact of the bridge closure on the community. The School St. pedestrian bridge between Medford St. and Highland Ave. will remain open for pedestrians and cyclists.
The GLX is a State project and therefore not subject to Somerville’s suspension of non-essential construction during the COVID-19 public health emergency. MassDOT has issued updated guidelines for its construction sites and workers.
