Bellefontaine Bridge

The Bellefontaine Bridge is a four-span truss railroad bridge over the Missouri River between St. Charles County, Missouri and St. Louis County, Missouri. It has four 440-foot (130 m) spans. Construction started on July 4, 1892, and it opened on December 27, 1893.[1]

The bridge was built by the Chicago, Burlington and Quincy Railroad[2] and is now owned and operated by BNSF Railway. New Jersey Steel & Iron Company of Trenton, NJ served as the contractor for the original construction, and George S. Morison designed the structure. Notably, the bridge was one of the first to use a Baltimore truss design; the nearby Merchants Bridge (also designed by Morison) used a Pennsylvania through truss design and had opened just a few years prior.[3] The truss spans are found on masonry piers, which were constructed atop caissons founded into bedrock below the river.[1]

The structure is the last railroad structure over the Missouri River before its confluence with the Mississippi River.
