I-75 remains closed this afternoon, following an accident involving a tractor trailer.

As motorists hit the road for the long holiday weekend, many anticipated slow travel and high traffic volumes on northbound highways in Michigan, but southbound travelers were surprised by the incident which closed the expressway at Corunna Rd. around 10 this morning.

Several callers indicated that traffic came to a standstill on I-75 southbound, and traffic backed up quickly. Police were able to guide some motorists to the Corunna Rd. exit.
