Fromberg Bridge, Spanning Clark's Fork of Yellowstone River on East River Street, Fromberg, Carbon County, MT

Significance: The first and only multi-span monumental reinforced concrete arch bridge built in Montana, the bridge facilitated the transportation of agricultural products (especially sugar beets) from the east side of the Clark's Fork River to the City of Fromberg and the Northern Pacific and Chicago, Burlington & Quincy Railroad lines on the west side of the river. The cement used for the bridge was supplied by the Gibson Culvert Company, a locally significant industry that pioneered the use of reinforced concrete in south central Montana. The bridge was the penultimate expression of Carbon County's experimentation with reinforced concrete and the progressive belief in efficiency, aesthetics, and permanence.
