Notes
  • Significance: The Sixth Street Viaduct is actually comprised of two separate structures: a pin-connected Pratt truss built over the tracks of the Chicago, Burlington and Quincy Railroad in 1886 and a girder overpass that was built as an approach in 1903-04. Both bridges are technologically significant as rare survivors of their type. The 1886 span is one of only three pinned through trusses remaining in Iowa's urban areas. Similarly, the open-web design of the 1903 girders is the only example of this uncommon configuration known to remain in the state. The viaduct as a whole is historically significant for its role in the development of downtown Burlington and its representation of the sometimes uneasy relationship between the city and the railroad that supported it.
