UPDATE: Highway 401 in Cambridge area will be closed into the afternoon

OPP say a crash involving a tanker truck carrying jet fuel has forced the closure of Highway 401 in both directions near Cambridge.  

Const. Robert Visconti says the truck was carrying 50,000 litres of highly flammable jet fuel when it rolled over early this morning after colliding with another vehicle in the eastbound lanes. 

It happened just before 2 a.m. and fuel spilled across both the eastbound and westbound lanes of the highway.   

Visconti says the highway is closed between Highway 6 South and Townline Road.   

He says the cleanup will take much of the day and the highway will not re-open until Sunday afternoon.  

The truck driver suffered minor injuries in the crash.
