Volkert provided construction engineering and inspection services on the recently completed bridge over the Tennessee River along U.S. 41 (S.R. 2) in Marion County, Tennessee. This included bridge replacement, roadway upgrades, and realignment.
Construction began in 2012 on the replacement of the existing truss structure originally constructed in the 1930’s. Cost of the project was $23 million, providing a new two-lane roadway with full shoulders.
Building the new one-mile-long bridge, which features two 12-foot lanes and full 10-foot shoulders, presented several distinct challenges.
The design and construction plans had to be altered to combat geotechnical issues. This added more than a year of additional work to the project and prompted the closure of the existing bridge, which was originally scheduled to remain open until completion of the new bridge.
Other challenges included the installation of a long steel girder, which spans over the main channel of the river, as well as the foundation and pier construction in water depths exceeding 80 feet.
Volkert provided project management and administration services, all aspects of construction inspection, materials testing, project documentation, utility coordination, erosion control and permit compliance, and traffic control inspection and documentation.
Demolition of the original bridge was recently completed with the blasting of foundations in the 80-ft deep main channel.
