KNOXVILLE, Tenn. (AP) - A highway that brings airport traffic to downtown Knoxville will remain constricted to one lane northbound.
A rock slide early Wednesday dropped debris on the right northbound lane of the Alcoa Highway, also known as U.S. 129. The driver of a truck which collided with the debris was treated at a hospital for a minor injury.
While the amount of rock was relatively small, the Tennessee Department of Transportation determined the wall it came out of is unstable, according to The Knoxville News Sentinel.
TDOT spokesman Mark Nagi said engineers are working on a plan to secure the rock face and an emergency contract should be let sometime after March 23.
Nagi said engineers don't think another slide is imminent.
