KINGSTON -- A section of Highway 401 eastbound near Kingston reopened Thursday evening after crews cleaned up a crash involving a tractor-trailer that caused liquid tar to leak into a wetland area.

Ontario Provincial Police say a truck carrying liquid tar struck the guardrail at kilometre marker 610 just before 5 a.m. and continued into the ditch.

The vehicle's fuel tanks were damaged and the contents of the trailer have leaked into the wetland area next to the highway.

Police say the driver of the truck was treated for minor injuries and charges are pending.

The Ministry of Environment is managing the clean-up of the liquid tar.

The highway was closed for approximately 14 hours, before reopening just after 7 p.m.
