Bellevue Bridge
The Bellevue Bridge (known as the Bellevue Toll Bridge and officially called the Grand Army of the Republic Bridge) is a continuous truss bridge over the Missouri River connecting Mills County, Iowa and Sarpy County, Nebraska at Bellevue, Nebraska. The bridge formerly connected Nebraska Highway 370 and Iowa Highway 370. Both routes were truncated upon the completion of the US 34 bridge downstream. The bridge was built in 1950 by the Bellevue Bridge Commission at a cost of $2.8 million (equivalent to $ million in ). The bridge charges $1 tolls for cars and is wide. Although the bridge is considered obsolete, there are no current plans to replace it. Various government entities have sparred over ownership, due to the expense of maintenance, after the initial bonds were paid off in 2000. The issue has been temporarily resolved since the Bridge Commission has had to seek more than $1 million in bonds for repairs to the bridge. See also *List of crossings of the Missouri Riv ...

Continuous Truss Bridge
A continuous truss bridge is a truss bridge which extends without hinges or joints across three or more supports. A continuous truss bridge may use less material than a series of simple trusses because a continuous truss distributes live loads across all the spans; in a series of simple trusses, each truss must be capable of supporting the entire load. Although some continuous truss bridges resemble cantilever bridges and may be constructed using cantilever techniques, there are important differences between the two forms. Cantilever bridges need not connect rigidly mid-span, as the cantilever arms are self-supporting. Although some cantilever bridges appear continuous due to decorative trusswork at the joints, these bridges will remain standing if the connections between the cantilevers are broken, or if the suspended span (if any) is removed. Conversely, continuous truss bridges rely on rigid truss connections throughout the structure for stability. Severing a continuous t ...
