Work continues to repair a massive landslide on I-75 at the Kentucky-Tennessee border.

In order to make the repairs near mile marker 143 on I-75 in Campbell County, Tennessee, southbound I-75 will remain closed. One lane of northbound I-75 will remain open.

The target date for one southbound lane and a second northbound lane to re-open is Monday, May 21. The Tennessee Department Of Transportation will continue to re-evaluate the situation, and adjust that schedule accordingly.

Crews are excavating and constructing a soil nail wall, which will require nails to be drilled as many as 50 feet underneath the Interstate. This is being done in order to stabilize the rock slope.

Currently, northbound I-75 has one lane of traffic open for approximately three miles, from mile marker 141 to mile marker 144.

Motorists should expect potential long delays and use extreme caution while traveling through this area.

TDOT recommends the following alternate routes and detours:

Detour Route for I-75 South: Take Exit 160 in Jellico, Tenn., follow U.S. 25W to LaFollette and back onto I-75 South at Exit 134 in Caryville.

Wide Load Detour Route for I-75 South: Take Exit 160 in Jellico, turn right and follow SR 297 West to SR 63 and back onto I-75 South at Exit 141.

Detour route for I-40 destinations east of Dandridge, Tenn.: Take Exit 29 at Corbin, Ky., follow U.S. 25E to Morristown, Tenn., take I-81 South to its junction with I-40.

However, U.S. 25E is reduced to one lane of traffic in each direction at the Kentucky-Tennessee border due to pavement repairs inside the Cumberland Gap Tunnel.

The Kentucky Transportation Cabinet will use portable message boards and dynamic overhead signs to advise motorists of possible delays.
