According to the Tennessee Department of Transportation, the repairs to the bridge will likely take three months. After TDOT crews examined the bridge, they determined the untouched portion of the bridge was still safe to cross, but the right lane of the road would remain closed until the necessary repairs can be made.

The diversion at Exit 23 will remain in place until traffic can be shifted overnight Tuesday, according to TDOT. Once the lane restriction is in place, TDOT said it will coordinate with Bell Construction and CSX for the months-long repair project.

One lane of travel is expected to remain open throughout the closure, according to TDOT. Some short-term, temporary full closures on the bridge may be required during the work, they added.

“TDOT is doing all it can to make the necessary repairs as safety and as quickly as possible while limiting the impact on traffic,” the department said in a statement.
