The Carrollton Bridge is a National Register-listed concrete arch bridge that was once considered too deteriorated and obsolete to be saved. Through the use of innovative engineering techniques, special materials, and experienced construction inspection engineers, the bridge was saved and rehabilitated with its original form. Travelway width was added to the bridge and safety was improved with approach railing.
The Carrollton Bridge carries Carrollton Road over the Wabash River, approximately three miles north of Delphi, Carroll County, Indiana. It was designed by Daniel B. Luten, an Indianapolis-based engineer, and was constructed in 1927. Along with the being the first permanent crossing over the Wabash River, it is the site of a historic Wabash and Erie Canal lock.
