Superior Avenue Viaduct
Why it's listed
Rising above the west bank of the Cuyahoga Valley in Cleveland, this sandstone arch viaduct was built between 1875 and 1878 to carry pedestrians, vehicles and streetcars across the river valley and to remove dangerous railroad crossings at street level. The original structure ran 3,211 feet and included ten Berea sandstone arches, a 322-foot cantilever swing bridge over the river, and a plate-girder approach on the east. City engineers E. W. Ensign and B. F. Morse designed it. It was among the largest engineering projects in the country at the time and was the first major structure to join Cleveland's east and west sides. The Detroit-Superior Bridge replaced its function, and in 1922 most of it was demolished. About 580 feet survives, including eight stone arches, with the eastern half barricaded. Local supporters have proposed turning the remnant into an urban park.
Significance in brief: The nomination argues it was one of the largest engineering projects in America when built. It was also an important symbolic link between Cleveland's east and west sides. Its cantilever swing bridge was the first major one in Cleveland, and the viaduct was the first major transportation and commerce structure to join the two sides of the city.

What listing means for this property
National Register listing is honorary: it recognises significance and does not restrict what a private owner may do without federal money or permits. It unlocks the 20% federal rehabilitation tax credit for income-producing buildings, state credits in many states, and Section 106 review when federal agencies are involved.
