UPDATE: The roadway has been cleared and all lanes are now open
The right lane has been reopened on I-75 south near mile marker 68 in Rockcastle County after an overturned semi caused all three lanes to be closed Tuesday morning.
Officials anticipate the middle and left lane to be blocked for another 1 ½ to 2 hours.
Police responded to a non-injury accident at about 10:30 a.m. to find a sedan slowed to almost a complete stop on the interstate after police said the driver became distracted.
The driver's actions caused the driver of the semi to hit the slow-moving car, causing the semi to overturn and block all three lanes of traffic.
Police said a large amount of coke, a coal derivative, was spilled from the overturned semi and a cleanup crew was called to help clean debris from the road.
Traffic was rerouted at exit 77 in Berea to Rt. 25 south back to Mount Vernon.
Police said a four-hour delay is expected as crews continue to work the scene.
