Ontario Provincial Police are warning of possible delays between Wawa and Sault Ste. Marie.
Superior East OPP say they responded to a single vehicle collision involving a transport truck last night: the tractor portion came to rest in the southbound lane of Highway 17 near Agawa Bay - and has since been removed - but the trailer remains off the roadway on a steep enbankment.
Crews are continuing to unload the contents of the trailer so it can be removed, but police warn that means the highway may be shut down intermittently until the trailer's removed.
