UPDATE: All lanes of Interstate 75 North in Campbell County should be open by the end of the day.

On February 26, rocks and debris rained down on the interstate just north of exit 141, the Oneida/Huntsville exit. TDOT initially closed both sides of the interstate to traffic because the slope was unstable.

They eventually reopened the southbound lanes on March 9, then allowed local traffic heading north to exit 141 to go beyond the detour closure at exit 134. On March 24, they opened one northbound lane to traffic.

The goal was to have both lanes reopened by Friday, April 15, but TDOT said Wednesday that the work was completed ahead of schedule and that the second lane should open later this afternoon.

TDOT says workers are on schedule to reopen the other northbound lane by Friday, April 15. However, work will still be going on in the area, so drivers will still need to use caution.

In the wake of the rock slide, drivers were forced to take long detours around the closure, or had to wait in traffic backups as they were forced to exit or merge into one lane of traffic.

PREVIOUS STORY: The Tennessee Department of Transportation says they will open one lane of Interstate 75 northbound in Campbell County Thursday, March 24, by 11:00am.

All northbound lanes have been closed since last month due to a rockslide that occurred at mile marker 142.

One lane will of I-75 NB will remain closed as work continues to remove slide debris, stabilize the existing slope, and repair the interstate. 

All southbound lanes were reopened March 10. The entire repair project is scheduled to be completed on or before April 15, according to TDOT.

PREVIOUS STORY: CARYVILLE, TN (AP) - Officials in Tennessee say the southbound lanes of Interstate 75 in Campbell County have reopened to traffic nearly two weeks after a large rockslide closed the roadway near the Kentucky border.

Media reported the lanes reopened Wednesday night. Tennessee Department of Transportation spokesman Mark Nagi says the northbound lanes remain closed.

TDOT awarded a $2.9 million emergency contract last week to Charles Blalock & Sons, Inc. The contract includes the removal of slide debris, stabilization of the existing slope and interstate repairs.

The contract stipulated that the road's southbound lanes reopen by March 17 and that at least one northbound lane re-open by March 24.

TDOT officials say the entire project must be completed by April 15.

PREVIOUS STORY: JACKSBORO, TN (AP) - Tennessee transportation officials are closing both southbound lanes of Interstate 75 just below the Kentucky state line.

A rock slide had caused the closing of 1 northbound and one southbound lane on Thursday. Tennessee Department of Transportation geotechnical engineers have since determined that an earthen embankment under the highway is sliding near the Stinking Creek exit at mile marker 144.

The closure will force thousands of southbound drivers to take a 26-mile detour through LaFollette to get around the site. It is expected to affect college students heading south for spring break.

TDOT planned to close the southbound lanes at 2 p.m. EST on Friday. There was no estimate about when the section might reopen.

TDOT spokesman Mark Nagi told The Knoxville News Sentinel (http://bit.ly/y8Kf40 ) southbound traffic on I-75 should take the Jellico exit at mile marker 160 and detour to exit 141 at Caryville.
