Ashtabula Viaduct, Spanning Ashtabula River at U.S. Route 20 (Prospect Road), Ashtabula, Ashtabula County, OH

Significance: This concrete, open spandrel rib arch viaduct is of engineering significance for its outstanding design feature of a complete separation of the superstructures at the end of each span using only abutting expansion joints. To accommodate the deck movement, long columns were used with a slenderness especially adapted. The viaduct was built by the Standish Engineering Company of Chicago, Illinois.
