If you are heading through Knoxville this morning on I-40, you will be detoured. TDOT says Interstate 40 is closed in both directions in downtown Knoxville after a tanker truck overturned carrying hazardous materials. Over the next few hours (as of 8 a.m. eastern this morning), crews will attempt to upright and offload the tanker. Interstate 40 west is closed at Interstate 275 and Interstate 40 East is closed at Interstate 640 on the west side of the accident. Traffic is being re-routed onto I-275 around downtown Knoxville. When cleared, westbound traffic will reopen while eastbound traffic will remain closed.
