Work crews will continue the series of rapid bridge superstructure replacements on I-93 in Medford beginning on Friday, July 8th at 8:00 PM and continuing through Monday, July 11th at 5:00 AM. This weekend’s locations involve the bridge on I-93 North over Webster Street and the approach spans on the bridge on I-93 North over the Mystic River.
Throughout the course of the weekend, traffic on I-93 will be limited to two lanes in each direction over a 6-mile segment between Exit 28 (Sullivan Square) in Somerville and Exit 36 (Montvale Avenue) in Stoneham. Traffic on I-93 North will be directed through a median crossover near the Somerville/Medford line and then travel in counter-flow operation on the southbound barrel of the highway before traveling through a second median crossover near Spot Pond in Stoneham. I-93 directional traffic will be separated by a moveable “zipper lane” barrier. Access to and from many of the ramps on I-93 North in this area will be restricted.
The $98.1 million project to replace these fourteen bridge superstructures in Medford is funded through the Patrick-Murray Administration’s historic Accelerated Bridge Program, a $3 billion recovery effort to reduce the Commonwealth’s backlog of structurally-deficient bridges.

Traffic is expected to be heavy throughout the duration of the weekend, particularly during daytime and early evening hours. MassDOT strongly recommends drivers that do not have a destination in the Medford/Downtown Boston area use alternate routes [I-495, I-95 (Route 128), Route 1 and I-90] to avoid the construction area.
Local Roadways & Waterways –
• Webster Street under I-93 will be closed to through traffic from Friday, July 8th at 6:00 PM through Monday, July 11th at 5:00 AM. West of I-93, local traffic seeking access to the east side of I-93 via Webster Street will be directed to use Forest Street and travel south to use Route 60 east or travel north to Roosevelt Circle and use Route 28 South (Fellsway). East of I-93, local traffic seeking access to the west side of I-93 via Webster Street will be directed to use Fulton Street north to Route 28 North (Fellsway) to Roosevelt Circle to Forest Street south.

• In the event of a safety concern with traffic congestion at intersections along Route 28 (Fellsway) or at other critical intersections impacted by detour traffic, State and local police details will provide traffic control to keep vehicular traffic moving and to provide safe crossings for bicycles and pedestrians.
• Wellington Circle (Route 28 (Fellsway) at Route 16 (Mystic Valley Parkway) will experience traffic congestion on Friday evening and throughout the daytime/early evening hours on Saturday and Sunday. MassDOT and the Massachusetts State Police request that motorists adhere to travel lane markings and yellow and red traffic signal displays to avoid blocking this intersection. Failure to follow this guidance will add to congestion and limit the ability of the traffic signals at this location to operate effectively.
