Chattanooga, Tenn. – I-24 East at mile marker 127 in Grundy County near the Coffee County Line is now open to traffic. The roadway reopened at approximately 6:00 a.m. CT Saturday, May 22. I-24 had been closed for several days as a result of a massive sinkhole that developed suddenly on the morning of Tuesday, May 18.
TDOT awarded an emergency repair contract to Highways, Inc. who worked around the clock to stabilize and repair the area. The initial sinkhole was 25’ deep and covered the entire inside lane and a portion of the outside lane of I-24 East between mile marker 127 and Exit 127. Crews had to excavate 35 feet to reach the bottom of the sinkhole and remove unstable material. The area was then filled in with more than 5400 tons of graded solid rock and repaved.
