Somerville City Planning Projects Underway

Improvement ProjectsGreen Line ExtensionThe final cut-over for the second of two Commuter Rail tracks between the Washington St. bridge and the Sycamore St. bridge is expected to take place the weekend of January 24.

Activities will include heavy equipment movement, hauling and dumping of crushed stone, and the cutting and welding of track. Overnight noise in these areas may be disruptive at times, primarily due to the use of gasoline-powered hand tools needed to cut tracks.
