The Ministry of Environment is cleaning up a diesel spill on Highway 10.
Grey County OPP say the fuel was spilled around 5 AM Monday when a tractor-trailer went into a ditch between Berkeley and Holland Centre.
No one was injured.
Highway 10 was closed for most of the day and will be down to one lane until Midnight north of Berkeley to Sideroad 50.
It will allow MOE crews to clean up the fuel.
