This bridge replaced a seven-lane steel girder bridge, constructed in 1960 by the Minnesota Highway Department. When it was built, it replaced a former bridge, located just to the east of the current bridge site, that carried US 65. Approaches to the former bridge had issues with flooding, with a 1965 flood putting the causeway just south of the bridge completely underwater. MnPass lanes were added in 2009.
