Later the British colonists developed Fort Western, an 18th-century stockade fort, adjacent to this site. It became the center of development for the city of Augusta.

Curran, a Catholic priest at St. Augustine Church in Augusta from 1962 to 1972. Long after his death in 1976, allegations of sexual abuse arose, which motivated the legislature to vote to remove his name from the bridge in 2009. The legislation to do so, sponsored by Rep. Patsy Crockett and signed by Gov. John Baldacci, gave the bridge its current name. The word calumet refers to a "peace pipe".
