MassDOT will close the Route 5 tunnel that passes under the Route 20 rotary adjacent to the North End Bridge in West Springfield at 9 a.m. Wednesday.
The tunnel will be closed in both directions for approximately six weeks for repairs, according to a news release from MassDOT.
Vehicles will be detoured off Route 5, and up the ramp to the rotary for Route 20 and the North End Bridge. Vehicles heading in both directions will travel through the rotary and rejoin Route 5 at the second rotary exit, the news release stated.
"The closure was required because of advanced deterioration in the tunnel's concrete driving surface. Numerous attempts to make interim repairs have demonstrated that more extensive repair efforts are necessary," the news release stated.
During the closure, the deteriorated portions of the roadway through the tunnel will be chipped to a solid base prior to filling with a special rapid setting concrete, which must be special ordered.
MassDOT encouraged drivers to allow for extra time when traveling through the detour and to be mindful of the additional vehicles traveling through the rotary.
