U.S. 41 Marion County Truss Bridge over Tennessee River to Close Today

Monday, January 09, 2012 | 03:15am

Chattanooga, Tenn. – At approximately 1:00 p.m. CST today, January 9, 2012, Tennessee Department of Transportation (TDOT) contract crews will close the Marion County truss bridge on U.S. Hwy. 41 over the Tennessee River at Nickajack Lake to all traffic until the new adjacent bridge currently under construction is completed.

Original plans called for the truss bridge to remain open as the new multi-span steel plate girder bridge was built. However, as construction progressed, crews found that some of the rock that was to support the new bridge piers contained voids and unsuitable material, resulting in the need to construct the footings deeper than originally planned. Because crews must excavate, drill, and blast to construct the new bridge piers, TDOT engineers determined that it is best for the safety of the traveling public and work crews to close the truss bridge to through traffic while this work is being performed.
 
A detour route that will add an additional 1.5 miles to the current route will be posted.
 
The prime contractor for the $21.5 million project is Britton Bridge, LLC of Mt. Juliet, Tennessee, and the estimated project completion date is February 2014.
 
Although motorists should plan for the existing bridge to be closed until that date, TDOT will inspect the existing bridge once the new piers are constructed to determine if it can safely be re-opened prior to completion of the new bridge.
