Massachusetts transportation officials are warning drivers that the Interstate 93 Tip O'Neill Tunnel will close in the southbound direction through Boston from late Tuesday night into Wednesday morning.
MassDOT is urging motorists to plan ahead for the closure by avoiding the area and seeking alternate routes. I-93 southbound traffic will be diverted to the Mystic Avenue offramp at Exit 28 for the detour route.
The closure will begin at 11 p.m. Tuesday and continue overnight into Wednesday. Motorists should expect delays and reduce speed along the detour routes.
Work to be performed includes power washing signs, ceilings and walls.
