Debris Removal and Rock Bolting Operations Continue

Knoxville, Tenn. –  Behind the scenes work has allowed the Tennessee Department of Transportation to temporarily open all lanes of U.S. 441 (The Spur) in Sevier County.
 
Emergency contractor Charles Blalock and Sons, Inc. is currently working offsite utilizing molds to pour concrete panels that will form a stained rock façade which will cover the recently constructed retaining wall. The retaining wall was built during phase one of the project to stabilize the rock slope above the roadway.
 
TDOT estimates crews will begin to install the rock façade during the week of March 15. At that time one southbound lane will close to allow crews to safely work on phase two of the rockslide repairs.

Knoxville, Tenn. – The Tennessee Department of Transportation re-opened one lane of US 441 (The Spur) southbound in Sevier County shortly before 3:30 p.m. this afternoon, nearly two weeks ahead of schedule. TDOT was forced to close the southbound lanes of the roadway after a rockslide threatened the stability of the mountainside on January 25. 
 
“We understand this has been an inconvenience to many people traveling to and from Gatlinburg and are pleased to see the contractor reopening the roadway ahead of schedule,” said TDOT Commissioner Gerald Nicely.
 
Since the rockslide occurred, motorists traveling southbound into Gatlinburg have been utilizing one of the northbound lanes. With the southbound lane now reopened, TDOT expects to remove the detour and reopen both northbound lanes to northbound traffic by Tuesday, weather permitting.
