The 5305-foot long Conde B. McCullough Memorial Bridge is a steel continuous cantilevered half-through truss with bracing above and below the deck. The cantilever design was adopted because high volumes of shipping made a draw span undesirable. Also, the wide shipping channel and high banks of both sides dictated a high-level bridge. The steel truss is 1708-feet long with the central portion being 793-feet and the anchor portions being 457.5-feet each. The top and bottom chords of the truss are curved in outline. The sway bracing is also curved, giving an impression of a series of Gothic arches as one travels through the truss.
Thirteen reinforced concrete deck arch spans with open spandrels flank the cantilevered spans, seven on the north side and six on the south side. The two lengths of arch approach spans total 2762-feet, with individual spans ranging from 151-feet to 265-feet in length. Reinforced concrete deck girder spans approach the arch spans. There are nine spans on the north end and five on the south. Ornate concrete abutments at each end of the bridge allow space along the road for travelers to pull over. The abutments also feature staircases that lead down under the bridge.
Length of largest span: 793.0 ft.
Total length: 5,323.0 ft. (1.0 mi.)
Deck width: 27.0 ft.
Vertical clearance above deck: 16.9 ft.
