Lincoln Avenue Viaduct, Spanning Union Pacific Railroad between Baring Cross Bridge & Union Station, Little Rock, Pulaski County, AR

Significance: Designed by the Missouri Pacific Railroad Company and presented to the City of Little Rock as a corporate gesture of goodwill, the Lincoln Avenue Viaduct was the first and only through rainbow arch in the city. As an example of a single-span reinforced concrete bridge of through rainbow arch design it remains today as an example unique in Arkansas. It was built by The Ozark Engineering Company of Joplin, Missouri in 1928 and, though it has lost a balustrade on the west side and has had a second bridge built adjacent to it, the Lincoln Avenue Viaduct is remarkably well preserved.
