Drainage and repaving work on eastbound Interstate 24 will mean night-time lane closures starting Saturday and continuing Sunday-Thursday through August, according to the state transportation department.
TDOT spokeswoman Jennifer Flynn said drainage work will begin early Saturday morning and the truck weigh station atop the mountain will be closed.
When the drainage work is finished, contractors will work nightly to mill and pave I-24 between mile markers 133 and 141, or all the way down the mountain.
The Tennessee Highway Patrol will assist with traffic control, and motorists are asked to use extra caution in the work area.
Flynn said the 6.36-mile project will cost $3.2 million and should be complete by Aug. 31.
