The Loudon County Bridge Project for SR73 (US321) included widening of a 1.71-mile section of SR73 to four lanes with the construction of three new bridges over the Tennessee River, Tellico Canal, and Norfolk Southern Railroad. The primary bridge was a welded steel girder spanning over 1500’ across the Tennessee River below the Fort Loudon Dam replacing the bridge across the dam. The Tellico Canal Bridge spanned 1100’ over a navigable section of the canal.
Large fleets of barges and cranes were used for the construction of the coffer dams and piers for both bridges. Bridgepoint (and formerly Southern States Survey) survey crews were responsible for layout of all structures and roadway sections including the lining of barges and temporary piers. There were also utility relocations and grade changes for TVA involved in the project. Charles Blalock and Sons was the prime contractor performing all aspects of the construction for the project and Tennessee Department of Transportation was the owner. We really appreciated Blalock’s confidence in us to stake this complicated project. Total Project Costs = $72 Million
