OPP close 401 near Chatham due to oil spill

An oil spill on Highway 401 caused heavy delays on Saturday afternoon.

Police say that a single vehicle collision that took place just after 10:00 a.m. prompted a police response in the area, which uncovered a previously undiscovered and substantial amount of oil on the highway, where an unknown vehicle had previously spilled.

The highway was closed to westbound traffic between Bloomfield Road and Queens Line.

Police have issued an advisory that motorists avoid the area, one lane is expected to open in the next couple of hours as crews clean the spill.

No injuries were reported.
