Travelers heading south into Tennessee via Interstate 75 should be prepared for a 26-mile detour.
On Friday, the Tennessee Department of Transportation closed both lanes of I-75 south at mile marker 160 near the Kentucky-Tennessee state line because a section of embankment had collapsed.
The transportation department said in a news release that the ground under the interstate had "continued to move since the collapse was discovered on Thursday."
The repairs might not be complete until 5 p.m. Mar. 23, according to a note posted on the department's Web site Saturday.
Drivers heading south on I-75 will take Exit 160 at Jellico, Tenn. They will then turn left and follow U.S. 25 West to LaFollette, then get back on I-75 south at Exit 134 in Caryville.
Signs have been posted to direct motorists. A map showing up-to-date traffic impacts in Tennessee is available at ww2.tdot.state.tn.us/tsw/smartmap.htm.
