WESTON, MASS. (WHDH) - Most of Route 95 south was closed to traffic in Weston after officials say a tractor-trailer accident resulted in polyurethane being spilled on the highway.

Massachusetts State Police said troopers and Weston Fire Department crews responded to the incident, which closed several lanes after a truck spilled a “load of polyurethane,” forcing traffic to be redirected through a breakdown lane some time before 10 a.m.

On Twitter, the MassDOT said the roadway spill was in the area of Exit 39A, by Route 30.

By 10:40 a.m., SKY7HD spotted several firefighters spreading sand across the spill, with a tractor-trailer truck pulled off to the side of the road, parked on a patch of grass. Heavy traffic could also be seen leading up to the site of the cleanup.

Authorities have not yet said whether there were any injuries, but advised drivers to expect delays.

Lanes started to reopen around 11 a.m., with officials stating both the left and center lanes were back open to traffic as crews continued their work.

All lanes of travel were back open by 11:45 a.m., according to MassDOT.
