By the mid-1970s, the C&NW bridge was rapidly becoming obsolete. It was nearly 100 years old, and could not support the ever heavier rail traffic. As a result, a plan was hatched where the C&NW bridge would be removed, and Burlington Northern would build a modern rail bridge over the Missouri River. The C&NW would have trackage rights on the new bridge in compensation for their bridge being demolished. The new bridge opened in 1982. Since that time, the C&NW was merged into the Union Pacific, which uses the C&NW trackage rights. The BN merged with the Santa Fe to become the BNSF Railway.
The BNSF Bridge is a heavy structure. The 425 foot main span is a single truss span. It is supported on two very hefty piers, which are needed to stand up to the spring floods and winter ice on the Missouri River. The main span is flanked by a number of plate deck girder spans that feature steel plates that are approximately 15 feet tall. The west end of the bridge is accessible from a city park. The east end crosses Interstate I-29, which limits any access to the east end of the structure.
