A high-traffic, two-lane crossing providing an east-west connection from the southwest section of Davidson and Williamson counties into Brentwood and Interstate 65, the existing bridge over Otter Creek on SR 254 in Davidson County had become structurally deficient and functionally obsolete after more than 50 years of service. Having worked on multiple projects together, TDOT solicited Gresham Smith’s guidance in determining the most feasible approach for repairing the aging structure. Turns out it was as easy as ABC.

A First-of-its-Type Method for the DOTAfter close collaboration with TDOT regarding the bridge’s current condition, we advised that the timeworn crossing was beyond repair, and that replacing the portion of the bridge that supported the deck was the only viable option. Because of the high traffic volumes along this stretch of SR 254 (Old Hickory Boulevard), we worked with TDOT to determine the most effective and expeditious way to carry out the bridge repairs.
It was ultimately decided that Accelerated Bridge Construction (ABC) offered the best solution. A first-of-its-type ABC method for TDOT, this short-term total closure of a 1-mile section of Old Hickory Boulevard would allow crews to carry out their work around the clock during a single weekend without being encumbered by road traffic.
