Project Pictures

This project extends 0.64 mile from First Ave. to SR-16 in Tullahoma, Coffee County. The typical section includes five (5) 11-ft lanes with curbs, gutters, and sidewalks. The project also includes the replacement of the existing bridge over North Fork Rock Creek and the Rock Creek Greenway. The existing structure is a 4-span, 156-ft long structure. The proposed bridge is a 2-span, 169.5-ft long structure. The new structure will be built along the existing centerline and is only about 15 feet wider than the existing bridge, presenting constructability concerns with the ability to phase-construct the bridge.

The detour around the bridge following state routes is 19 miles long. While there is a shorter detour using local roads, TDOT cannot use local roads to detour state route traffic. However, local and truck traffic may choose not to follow the marked detour route and take the shorter detour along the local roads, which would impact local road traffic and maintenance.

Other challenges to the project include utilities, historic properties, the Rock Creek Greenway, and hazardous materials. Several overhead and underground utilities run along the corridor and the existing bridge. Overhead utilities also cross the roadway along the eastern bridge abutment.

Two historical properties have been identified on the project: the Oakwood Cemetery (Tract 36) and the Coca-Cola building (Tract 33). The proposed impacts to these properties have both been coordinated with the State Historic Preservation Office, but any changes to the impacts would require additional coordination.

The Rock Creek Greenway must remain open and operational at all times during construction. A detour plan has been developed which will connect the greenway to the existing sidewalk on SR-55, cross the state route, and tie back to the greenway on the other side of the bridge.

Finally, hazardous soils have been identified in the area of Tract 26 due to a leak from underground storage tanks. The storage tanks have been removed, but if contaminated soils are encountered during construction, their proper disposal must be coordinated with TDOT Environmental Division and TDEC Division of Solid Waste Management. Tract 26 is in the vicinity of the eastern bridge abutment, and up to approximately 700 CY of material may contain contaminated soils, but the actual amount will not be known until the soil excavated and tested.

The right-of-way acquisition for the project is currently underway. The roadway plans are approximately 80% complete, but drainage design is still preliminary (approximately 50% complete). Bridge plans are only at the Preliminary Layout stage of development.

Given the long detour and many other challenges and constraints, the Department is seeking recommendations from contractors on the best bridge design and method of construction which will limit the duration of any road closures and reduce impacts to the traveling public. The focus of the Constructability Review will be the bridge. The Department’s goal is to have a clearly defined duration of any impacts which can be communicated to the public prior to construction. The Department would like recommendations on the potential use of innovative delivery and/or construction methods, such as Accelerated Bridge Construction, A + B, Phase Construction, Design/Build, or CM/GC, and assistance with identifying the potential risks of each method.
