MassDOT says beginning at 11 p.m. Saturday night through 6:00 a.m. Sunday morning, all westbound lanes will be completely closed at Exit 45 and traffic will be detoured to I-91. The detour will take drivers to the Westfield Mass Pike on-ramp.
Crews will be conducting bridge repairs in the area. However, the construction is weather dependent. Signs for the detour will be posted throughout West Springfield, Holyoke and Westfield.
