This is large cantilever truss bridge. The southernmost span of the main continuous cantilever structure is slightly inclined, and this can be seen by observing the angles that the bottom chord assumes. Unlike some cantilever bridges however, the overall deck is not visibly cambered.

Although a memorial plaque on this bridge lists a 1950 date, this is not when the bridge was built. The date may reference when the memorial name was applied to the bridge, rather than when the actual bridge was constructed. The National Bridge Inventory provides a 1930 date, which seems appropriate for the construction of this bridge. The bridge was rehabilitated in 1993, and later starting in 2007 during a project that repainted the bridge a vibrant green.

A modern cantilever truss bridge at this location carries northbound traffic, while the historic bridge carries southbound traffic.

The bridge's extensive overhead bracing and built-up beams with extensive v-lacing and lattice give the bridge a beautiful geometric complexity. Its a striking contrast to the plain, simple appearance of the modern northbound bridge.

The bridge includes a series of approach spans. The most significant approach span is a simple span Warren through truss span, which is an extremely rare example of a Warren through truss with no vertical members.

Given the widespread and generally relentless destruction of historic cantilever truss highway bridges on the Ohio River, this bridge is an increasingly rare example of its type, and today one of the oldest highway cantilever trusses surviving on the Ohio River. Therefore, it is hoped that this bridge will continue to be maintained.
