6-Month Somerville Ave. Detour (Between Dane St. and the Somerville Ave./Washington St. Intersection) Begins Tuesday, February 19

As part of the next phase of the Somerville Ave. Utility & Streetscape Improvements Project, City contractors will set up a large work zone in Union Square on or around February 19. It will remain in place for approximately six months.
For the duration of this six-month period, eastbound through traffic on Somerville Ave. will be detoured onto Dane St. and Washington St., although vehicles will still be able to proceed up to the Warren Ave. intersection to access residences, businesses, and on-street parking.
MBTA bus stops on routes 85 and 87 between Dane St. and Union Square will be temporarily closed and relocated.
Westbound through traffic will be maintained, as will pedestrian and bicycle traffic in both directions.
This detour will allow crews to install the first section of a stormwater box culvert along Somerville Ave. between Bow St. and Washington St. This structure, which will ultimately extend east to Poplar St., will support nearly two-thirds of the City’s drainage and help minimize flooding in the Union Square area.
