JACKSBORO (WATE) – The Tennessee Department of Transportation (TDOT) has awarded a $2.9 million emergency contract to repair a rock slide on Interstate 75 in Campbell County to Charles Blalock and Sons Inc.

TDOT says the southbound lanes reopened just after 7 p.m. Wednesday. Recently, Interstate-75 North at Exit 141 re-opened to local traffic only.

The northbound detour via Exit 134 will stay open. Drivers going north should take exit 134, follow US-25W to Lafollette and Jellico, reentering I-75 at exit 160. TDOT believes one northbound lane will reopen on or before March 24.

Feburary’s slide at mile marker 142 sent vehicle-sized rocks falling into both the northbound and southbound sides of the interstate. The contract includes removing slide debris, stabilizing the existing slope and repairing the interstate.Previous story: Slope slide forces the closure of all four lanes on I-75 in Campbell County

The contract also specifies the southbound lanes must be open within 14 days and one lane northbound within 21 days. The entire project is set to be complete on or before April 15.

Originally, TDOT spokesman Mark Nagi says traffic cannot detour onto exit 141 because that would lead tractor trailer traffic onto SR 297, which isn’t wide enough to handle tractor trailers in both directions. Also, an accident on SR 297 that shuts it down would cause traffic gridlock that could last for a very long time.
