The Tennessee Department of Transportation (TDOT) has awarded two Alternative Delivery contracts for the reconstruction of three East Tennessee bridges destroyed by Hurricane Helene in September. Following a successful Guaranteed Maximum Price (GMP) negotiation, TDOT has entrusted Kiewit Infrastructure South Co. of Brentwood, Tennessee with a Progressive Design-Build (PDB) contract for the rebuilding of the SR-81 bridge in Washington County and the SR-107 bridge in Greene County. The contract is valued at $56,546,444.33, and both bridges are scheduled to open before the end of June.
Additionally, TDOT has awarded a Design-Build (DB) contract to Summers-Taylor, Inc. of Johnson City, Tennessee for the reconstruction of the SR-353 bridge in Washington County. This contract is worth $20,970,200.00, and the bridge is expected to be operational by the end of May 2026.

The replacement of these bridges, which span the Nolichucky River, is crucial for residents of Greene and Washington counties, as they connect the communities of Greeneville, Jonesborough, and Erwin. The projects are made possible by the Transportation Modernization Act (TMA) and utilize the Progressive Design-Build approach, which involves collaboration among the owner, designers, and builders early in the project lifecycle, potentially leading to faster completion.
The Design-Build method combines various project phases into a single contract, which TDOT is employing to expedite delivery and streamline design processes. Federal reimbursement for the $510 million total repair cost has been allocated, with TDOT receiving $102 million.
