Until 2014, it carried U.S. Highway 34 across the river. The bridge has seven spans, including the {{convert|402|ft|m|adj=on}} cantilevered through truss over the river's navigable channel. It is anchored by {{convert|201|ft|m|adj=on}} through spans, with two {{convert|203|ft|m|adj=on}} and two {{convert|104|ft|m|adj=on}} deck trusses over the eastern flood plain. The bridge has clearance of {{convert|14|ft|5|in|m}}[2] and a width of {{convert|20|ft|m}}. The bridge was built in 1929, replacing a ferry that previously operated at the site. It was designed by the Omaha Structural Steel Works. In November 2006 it was decided to repair the bridge rather than build new bridges. Earlier plans had called for a new $42 million two-lane bridge and bypass of Plattsmouth.[3] The new bridge would have been about {{convert|300|ft|m}} south of the existing one. In November 2007, ownership of the bridge was transferred from the private Plattsmouth Bridge company to the public Plattsmouth Bridge Commission.[4] Between April 21, 2008 and November 9, 2008, the bridge was closed as part of a federally funded bridge restoration.[4] The bridge reopened November 9, 2008.[5] As of 2011, the toll for cars was $1.25.[6] In 2018, the toll for cars was raised to $1.75.[7] In 2014, Highway 34 was rerouted to a new four-lane bridge farther upstream, north of the Platte River and above its junction with the Missouri.[8][9] See also
