The new bridge carries relocated US 34 over the Missouri River north of Plattsmouth, Nebraska. The $61M bridge has 18 spans resulting in a total bridge length of 3,280 feet. The main span over the navigation channel is 515 feet in length, and the roadway width is 86 feet to accommodate two lanes of traffic in both the EB and WB directions. The bridge has four units, with the river span unit being comprised of 3 spans of haunched steel plate girders. The steel unit utilizes five main load carrying girders with a sub stringer system. The remaining three units for the Nebraska and Iowa approaches are comprised of 150 pre-stressed concrete girders. The steel unit is supported on 4 large hammerhead piers. The river piers are supported on 48 inch diameter pipe piles and the remaining substructure elements are supported on steel-H piles. HDR performed the design of the new bridge as well as conducted a corridor study and the Environmental Impact Statement for the new bridge. The geotechnical design services were provided by Kleinfelder, a member of HDR's Design Team, and the Jensen Team, for the US-69 Design Build project. Kleinfelder's services included geotechnical exploration and design recommendations for the bridge foundations utilizing H-piles and pipe piles
