Replacement of the SR-81, SR-107, and SR-353 bridges over the Nolichucky River, destroyed by Hurricane Helene, is critical to Greene and Washington County residents, as they provide connectivity between the Greeneville, Jonesborough, and Erwin communities.

Made possible by the Transportation Modernization Act (TMA), the Progressive Design-Build approach is a project delivery method that involves a Design-Build team early in the project’s lifecycle. This method allows the design and construction phases to overlap, facilitating continuous collaboration among the owner, designers, and builders.

This approach can lead to faster project completion.
