Massman Construction Co. was awarded a contract from the Tennessee Department of Transportation to replace and subsequently remove the existing Slingo Bridge across the Caney Fork River arm of Center Hill Lake in Central Tennessee. 

The new bridge is a 1,545-foot continuous span, 8.5-foot deep plate-girder bridge with five equal spans supported by two abutments; three piers in the lake and one pier on land. The three water piers required drilled shafts that extend down 160 feet below normal pool. The concrete substructure included a the 30-foot tall shaft extension above each drilled shaft.
