CORNWALL – It could be hours before a section of Highway 401 is reopened just west of here after two tractor-trailers smashed into each other spilling tar on the highway. Police say the crash happened near Power Dam Drive. Pictures from the scene depict the two rigs as heaps of twisted metal. Amazingly, there were only minor injuries associated with the wreck. The traffic was backed up for several kilometers and was as far back as Boundary Road as of 8 p.m. Traffic was being detoured on Brookdale Avenue and County Road 2.
