Provincial police are advising drivers to avoid Highway 401 in the Napanee area after a pile-up involving multiple cars and tractor trailers Wednesday morning.
The eastbound and westbound lanes of the highway were closed off between Highway 41 and Deseronto Road in the community east of Belleville.
Fire officials said the pile-up involved about twenty vehicles and stretched nearly half a kilometre along the 401. At least 6 people had to be transported to hospital for various injuries.
A bus had been sent out to pick up and shelter stranded motorists.
Police warned drivers on the highway in that area to slow down and follow signs for the detour route.
The highway was expected to be closed for several hours.
