BB&A provided structural design and contract plan preparation for this value engineering change proposal for this bridge over the new 12.5 mile, six-lane south extension of the Veteran's Memorial Tollway. Gougar Road Bridge is a new two-span structure over the extension with span lengths of 203 feet.

This design employed mid-span splicing where the girder segments are erected on temporary shoring towers and post-tensioned in stages. The project included substituting the original 4-span, 200’, 230’, 230’, and 200’ steel girder system with a 2-span structure utilizing 90-inch spliced post-tensioned PPC beams. The originally intended end spans were replaced with embankments and the cast-in-place concrete wingwalls were replaced with MSE walls.
