In order to conduct necessary but unforeseen gas service line repairs, MassDOT and Eversource contractors will need to continue the closure of Beacon St., between Oxford St. and Park St., for approximately 4 weeks. Between the hours of 7 a.m. and approximately 3:30 p.m., Monday through Friday, neither vehicles nor bicycles will be able to access this portion of Beacon St. Eastbound traffic will be detoured on Somerville Ave. to Park St., and westbound traffic will be detoured at Park St. to Somerville Ave.
Abutters and patrons of local businesses will able to access Beacon St. to Sacramento St.
After work hours, all traffic will be allowed through the work zone, however please note that the road within the work zone will not be paved, and we advise all traffic to consider using the detour where possible. Additionally, cyclists are asked to consider utilizing the City's recommended detour, found at the bottom of this page.
Full-Depth Reconstruction Starting May 2016
In 2016, MassDOT will begin a full-depth reconstruction of Beacon Street, which will improve the lifespan of the road by rebuilding the sub-surface, grading the surface for positive drainage, and installing a new high-quality asphalt surface. The roadway design will improve the safety and flow of traffic, while dramatically improving pedestrian accessibility and bicycle safety.
Improvements Above and Below Ground
Improvements will include:
A full-depth reconstruction means that crews will dig all the way down to the base layer to completely replace the roadway. The new surface will thus be far less prone to pot holing than it is currently.
In 2015, water and sewer pipes were repaired using a cutting-edge, trenchless method to give the existing pipes a new structural lining. This involves injecting a coating into the pipes that lines the old pipe, hardens, and effectively creates a new pipe within the old pipe. The method requires less time, money, and excavation than traditional dig-and-cut pipe replacement.
Building a Better Bike Lane
Beacon Street reconstruction is Somerville's first roadway project that will include an exclusive bike lane that is separated from the roadway and traffic. Unlike bike lanes marked by a stripe of paint, separation can be achieved through pavement markings, curbs/medians, on-street parking, bollards, or a combination of these elements.
The bike facility type is supported by the National Association of City Transportation Officials (NACTO) Urban Bikeway Design Guide , Federal Highway Adminisrtation (FHWA) Separated Bike Lane Planning & Design Guide , and MassDOT's Separated Bike Lane Planning and Design Guide .
Balancing Multi-Modal Needs
Parking will be removed to balance multi-modal needs along this busy corridor. On street parking on the even side of Beacon Street between Oxford Street and Museum Street will be preserved, but on-street parking on the odd-side between Oxford and Museum will be removed. Between Museum Street and Park Street that alignment will flip: on-street parking will be preserved on the odd-site, but removed on the even-side. Between Washington Street and Dickinson Street, on-street parking will be preserved on both sides of the street. Based on current use levels, a parking study determined that enough parking capacity would remain in the area despite this reduction in spaces.
As of 2015, the league of American Bicyclists ranked Somerville #3 in the country and #1 in the region for the percentage of bike commuters at 7.8%. The City's semi-annual Bike and Pedestrian Counts have repeatedly shown Beacon Street to be the city's most heavily used corridor with over 500+ cyclists during peaks hours. The installation of the separated bike lane will promote traffic safety for all road users while supporting the ever-increasing bicycling volumes along this multi-modal corridor.
Coming Construction Updates
The City encourages cyclists to use alternative routes during the construction. A recommended detour route has been prepared in partnership between the Somerville Traffic & Parking Department, the Somerville Police Department, and the Somerville Bicycle Advisory Committee. These routes will be marked with vertical signage.
