UPDATE: Corbin firefighters say the wreck that has northbound Interstate 75 shut down at the 28-mile marker should be cleared within the next hour.

Captain James Smith said at 4 p.m. that the four passenger vehicles involved in the wreck have been removed from the scene.

The fifth vehicle involved was a tractor-trailer truck hauling a full tanker of gasoline.

“The semi was not drivable,” Smith said, noting it has been moved to the side of the road, but another truck is being brought in to haul away the trailer.

Smith said the wreck was a chain reaction as traffic began backing up.

Both lanes of traffic were blocked.
