State Route 1 (US 70) Broadway Viaduct
Davidson CountyUPDATE: Bridge Partially Reopened
The bridge partially reopened Thursday, September 7, to two lanes of traffic in each direction. Check out a LIVE view of the bridge HERE.
Kiewit crews have replaced the structure, completing roughly 95% of the project. They were able to accomplish more than expected within the eight-week time frame.
Between now and Oct. 31, work will continue on and beneath the bridge where crews will finish the fencing, railing, and lighting among other items. That work will require intermittent daytime closures of 11th Avenue from Porter Street to McGavock Street from 9 a.m. to 3 p.m.
BRIDGE CLOSURE
The Broadway Bridge will be closed July 7 until September 8, 2023. The bridge will be closed from 8th Avenue to 13th Avenue. Eleventh Avenue will also be closed from Porter Street to McGavock Street.
During the 8-week closure the bridge will be totally replaced. It will be partially reopened in September returning it to its narrowed configuration of two lanes open in each direction. Crews will then tackle final items like sidewalk construction, bridge railing and lighting until the project completion date of Oct. 31, 2023, at which point the bridge will be fully reopened to is final configuration of three lanes open in each direction.
Drivers are encouraged to utilize Demonbreun St. and Church Street as a primary detour route around the closure. TDOT is working with NDOT, Metro Police and other participating stakeholders to monitor the detour route and manage traffic accordingly.

Project Overview
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.
Design
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.
