The Elkader Keystone Bridge is a historic stone arch bridge on Bridge Street in Elkader, Iowa, crossing the Turkey River. In 1888 the old iron truss bridge was found unsafe, so the Clayton County Board of Supervisors funded a new limestone bridge to save money and provide a reliable crossing. Designed by engineer M. Tschirgi and built by Dubuque stonemasons Byrne and Blade, it was completed in 1889 at a cost of $16,282 and spans 346 feet. It is one of the largest twin-arched keystone bridges west of the Mississippi. A sidewalk was added on the north side in 1924. The bridge was added to the National Register of Historic Places on November 7, 1976 (reference number 76000747).
