2015 Grand Iris Winner - Gresham, Smith and Partners

Grand Iris Award Winner

(Bridge over Otter Creek on SR 254, Nashville, TN )

An 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. Gresham, Smith and Partners served as the design firm for the improvement project which included minimal roadway widening, substructure modifications and full superstructure replacement and widening for an existing two span structure. The plans developed replaced the existing structure with a single-span superstructure and provided for two precast units to be installed and joined over a single weekend closure in what was the first of its type Accelerated Bridge Construction project undertaken by TDOT.
