Crews are working to off-load a tractor trailer loaded with bottled water, which rolled over early Wednesday on Bruce Road 3 just north of Mildmay.
The water has to be unloaded before the truck can be lifted back up-right.
South Bruce OPP say the crash has blocked Bruce Road 3 between Highway 9 and sideroad 21-22 of Carrick township.
It’s expected the road will be closed most of the afternoon.
The female truck driver suffered minor injuries.
