Minneapolis Union Railway Stone Arch Bridge plans (N 128), Northwest Architectural Archives, University of Minnesota Libraries, Minneapolis.
The Stone Arch Bridge was built in 1883 by James J. Hill's Minneapolis Union Railway to allow for increased movement of people and goods across the Mississippi River. The bridge is situated just below St. Anthony Falls and served as a working railroad bridge until 1965. The bridge is made of native granite and limestone, measures 2100-feet long by 28-feet wide and consists of 23 arches. It is the only stone arch bridge ever constructed to span the Mississippi River.
The collection contains three blueline sheets, one of the Minneapolis Union Railway Viaduct, one plan showing two spans of the Stone Arch Bridge (Stone Viaduct) across the Mississippi River and one plan for cutting of ringstones and courses.
An unpublished finding aid with detailed contents is available in the Manuscripts Division.
