The bridge has seven spans, including the 402-foot (123 m) cantilevered through truss over the river's navigable channel.

It is anchored by 201-foot (61 m) through spans, with two 203-foot (62 m) and two 104-foot (32 m) deck trusses over the eastern flood plain.

The bridge was built in 1929, replacing a ferry that previously operated at the site.

Earlier plans had called for a new $42 million two-lane bridge and bypass of Plattsmouth.

[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.
