Each of the verticals is 34m long and weighs 20t; the first bottom chords of the truss, 30m long and weighing 55t, have also been erected. The bridge will be built by the balanced cantilever technique. It will cross one of the deepest parts of Lake Cumberland but the contractor has avoided the need for falsework bents in the 55m-deep water by connecting them to the pile cap. Massman Construction was responsible for the substructure contract.

Superstructure takes shape on Cumberland Lake Bridge
The first verticals have been erected for construction of the superstructure for the new Cumberland Lake Bridge in Kentucky, USA. Main contractor American Bridge has a US$49 million contract to build the new bridge, carrying out all the steel erection for the 479m-long, two-span continuous truss which weighs more than 11,000t. The existing bridge will be demolished once the new structure is complete.
