Complete Overnight Closure of I-93 Southbound Tunnel Tuesday Night

All lanes of the I-93 southbound tunnel through Boston will be closed overnight Tuesday into Wednesday.

Starting Tuesday, Sept. 22 at 11 p.m. overnight into Wednesday, Sept. 23, state officials say the Massachusetts Department of Transportation’s maintenance schedule will require complete lane closures of the Interstate 93 Southbound Tunnel through Boston.

Beginning on I-93 Southbound, traffic will be diverted from the Mystic Ave Offramp at Exit 28, to begin along the detour route. Upon exiting the offramp, all traffic will be directed through Sullivan Square to Rutherford Ave, following to the Surface Artery Southbound. At that point, traffic will return to the onramp from Albany Street at Herald Street returning to I-93 Southbound.

The full closure will begin at 11 p.m. on Tuesday, Sept. 22, and last until 5 a.m. Wednesday, Sept. 23.. In the event of inclement weather, the closure will be postponed.

MassDOT encourages drivers to avoid the area and seek alternate routes to minimize delays. Those traveling through the area should expect delays and should reduce speed and use caution while traveling along the detour routes.

Work to be performed includes roadway sweeping, wall and sign washing.
