State Route 1 (US 70) Broadway Viaduct

Davidson County


The project along State Route 1 (US 431) consists of replacing the bridge, also known as the Broadway Viaduct, that crosses over 11th Avenue and the CSX Railroad in downtown Nashville, Davidson County.


Purpose and Need

Broadway is an urban principal arterial. Built in 1948, the existing Broadway Viaduct, the structure crossing over 11th Avenue and the CSX Railroad, is showing signs of deterioration and needs to be replaced.

The purpose of the project is to replace the existing structure.

Bridge Rendering


The existing structure is approximately 700 feet long and 98 feet wide. It’s comprised of structural steel beams and support columns. The roadway consists of six 10-foot travel lanes (three in each direction) and one 12-foot center turn lane and 10-foot sidewalks. 

The replacement structure will remain on the same alignment and general width of the existing structure. It will be comprised of steel girders and support columns. The roadway will maintain six 10-foot travel lanes (three in each direction) an 8-foot striped median with one-foot shoulders, curb and gutter, and 11-foot 8-inch sidewalks, which includes space for aesthetic features like planters on both sides of the roadway.

The additional space will allow for planters to be placed on the sidewalk, separating vehicular and pedestrian traffic. The design includes the possibility for connections to future development in the area.

Project Delivery

The project is located along the heavily traveled Broadway corridor, an important route to traffic flow in and out of downtown Nashville. It is also in close proximity to developments, historic sites, and active CSX rail lines. In an effort to reduce construction impacts, accelerated bridge construction techniques and alternative delivery methods are being considered.
