KINGSTON, Tenn. – All lanes on Interstate 40 in Roane County are now open following the repair of a sinkhole that developed in the road’s shoulder.
The leftmost eastbound lane in Roane County between Exit 355/Lawnville Road and Exit 356/Gallaher Road was closed about 9:30 a.m. Thursday after workers found the sinkhole while mowing along the interstate, TDOT spokesperson Julie Oaks said.
“Our geotechnical engineers believe water flowing through the ditchline in the median seeped down into a depression in the rock under the roadway over the years,” Oaks said.
After repairs, the road was reopened at 6:30 p.m. Thursday, Oaks said.
