State Route 1 (US 441) Broadway Viaduct

Knox County

NOTICE: The Broadway Viaduct CLOSED on Sunday, November 3, 2019. All traffic is now detoured. A community outreach meeting was held on Thursday, October 17, to discuss the closure and its impacts. For more information, visit the Public Involvement section of this website.

Overview

The project for State Route 1 (US 441/Broadway) over the Norfolk Southern Railroad in Knox County, also known as the Broadway Viaduct, includes the replacement of the existing bridge, covering approximately 0.23 miles.

Purpose and Need

Originally built in 1927, the Broadway Viaduct is a critical connection between the communities of North Knoxville and South Knoxville. Today, traffic counts along the connector route average 10,090 vehicles per day. The bridge shows signs of deterioration, and both vertical and horizontal clearances are at or below current standards.

A new bridge is necessary to replace the aging structure and correct clearances. The planned design will improve the safety and operation of the viaduct, while providing a facility that meets multimodal traffic demands.

Design

The existing bridge is a 746-foot long concrete structure, spanning five railroad tracks and providing four vehicle travel lanes (two in each direction). Several buildings are either attached to the bridge or have minimal clearance with the existing structure.

The planned design consists of replacing the outdated bridge with a new, 62-foot wide structure consisting of two 11-foot travel lanes with a dedicated center turn lane, bike lanes, and sidewalks. The new bridge will be constructed with a clearance of 23 feet.

During construction, special measures will be taken to minimize impacts to nearby buildings and businesses.

Closures

Due to the location of the project and the nature of the work, the Broadway Viaduct will be closed to all traffic for the duration of the project. During the closure, Broadway will be closed from the intersection of Oak Avenue, Worlds Fair Park, and Jackson Avenue to just north of the Depot Avenue intersection. Depot Avenue will also be closed. These closures will ensure the safety of workers and motorists as crews demolish the old bridge and reconstruct the new bridge.

Additional lane closures on local streets may also be necessary as crews move to different parts of the project. Detours on local streets will be dependent upon specific bridge work.

Detours

During construction, all traffic will be detoured via the primary detour routes or the local detour routes.
