KNOXVILLE, Tenn. (WVLT) -- A large boulder that fell onto Interstate 40 late Monday morning has shut down a westbound lane in Roane Co. The boulder came down during a rock slide, blocking the right hand lane of the interstate, near mile marker 343 around 9:30 a.m.
TDOT dispatched a trackhoe with a rock hammer to break the boulder into smaller pieces so they can be more easily removed by TDOT Maintenance. They hope to have the lane reopened by 9:00 p.m. Monday night.
A TDOT spokesperson said their geological engineers do not believe any more large pieces of rock will fall from the slope. They have put up concrete barricades to contain any loose materials from the slope.
