'Extreme heat' causes road damage on Hwy. 402

As extreme temperatures grip southwestern Ontario, a section of Highway 402 in Lambton County is closed due to damage caused by the heat.

OPP say officers responded on Sunday evening just after 6 p.m. after receiving a report of unsafe road conditions on the westbound side of the highway. Temperatures that day exceeded 30 C.

A spokesperson for the Ministry of Transportation, which oversees the highway, said that due to the heat a pavement joint needs to be repaired. 

The highway is closed between Oil Heritage Road and Mandaumin Road but a detour has been set up for traffic.

The area is expected to reopen later this week and permanent repairs will be made in the fall, the spokesperson said.
