Our bridge team provided design and construction plans for this 2,244-foot-long bridge over the Missouri River.
The new bridge, which features a 44-foot roadway and an 8-foot protected bikeway, replaced a narrow and obsolete bridge built in 1930.
The bridge deck measures 55 feet, 4 inches wide and flares to 71 feet, 8 inches at the south end. The layout of the bridge consists of two prestressed concrete girder approach spans of 122 feet; a welded plate girder river unit with spans of 340 feet, 460 feet, 425 feet and 315 feet; and four prestressed concrete girder approach spans that average 115 feet.
The river piers are hammer head style, also known as a solid shaft pier, with drilled shaft foundations. The approach span piers include a hammer head on steel pile, three columns on steel pile, and four columns, each on a single-drilled shaft. The seismic design is Category B.
