FROM TDOT:
All Lanes Are Open on I-40 in Roane County
Sinkhole is successfully repaired before holiday traffic ensues
KNOXVILLE, Tenn. – The Tennessee Department of Transportation opened all eastbound lanes on I-40 in Roane County shortly after 6:30 p.m. after repairing a sinkhole that developed in the shoulder.
The left lane of I-40 eastbound in Roane County between Exit 355 (Lawnville Road) and Exit 356 (Gallaher Road) was closed while TDOT crews repaired a sinkhole in the shoulder.
TDOT crews discovered the sinkhole shortly before 9:00 a.m. Workers dug under the surface to find a weakness that spanned 14 feet wide and approximately 15 feet deep. TDOT geotechnical engineers believe over the course of several years, water flowing through the ditch line in the grassy median seeped into a depression and into the bedrock below the median and shoulder weakening the soil.
