TDOT Opts For Total Closures To Expedite Nashville Overpass Replacement

Apr 14, 2015

During 13 weekends between mid-2015 and early 2016, roadwork will shut down the interstate loop west of downtown Nashville, as crews replace crumbling bridges over four surface streets.

Tennessee highway officials say partial closures of the highway would draw out traffic delays on I-40 for years.

“These bridges are prime examples of aging infrastructure, and they are long overdue for major work,” TDOT commissioner John Schroer said in a statement. The structures were built in 1968 and have required increasing levels of maintenance.

TDOT released a video showing how the expedited process will work. On Friday nights, the interstate will close between the I-40 and I-65 splits. One of the eight spans — four streets, two directions each — slated for replacement will be demolished and hauled away. Prefabricated panels will be placed on the existing supports.

If all goes as planned, the concrete will cure in time for all lanes to reopen before Monday morning's rush hour.

TDOT officials say the work will not interfere with major travel weekends during the CMA festival and July 4 festivities. But they won’t know exactly which weekends will have closures until two to three days ahead of time.
