One of three locks on the chain link fence that borders the walkway of the swinging bridge that spans the Androscoggin river and connects Brunswick to Topsham Maine. Not exactly a full fledged tradition yet.

The Swinging Bridge in Maine was originally built in 1892 for workers walking from the Topsham Heights neighborhood to Cabot Mill in Brunswick, over the Androscoggin River. The bridge was constructed by John A. Roebling's Sons Company, the engineering firm that designed and built the Brooklyn Bridge in New York City and other bridges around the world. The bridge's history is closely tied to the French Canadian heritage of Topsham and Brunswick.

In the early 1900s, the present steel towers replaced the original timber-framed towers. A flood destroyed the superstructure of the bridge in 1936 and it was rebuilt in 1938 by the WPA. The current cables date all the way back to when the bridge was first built.

The towns of Brunswick and Topsham created a joint committee to repair the bridge in 2000. The bridge renovation was completed in December 2006. Public parks on each side of the bridge were completed in summer 2007.
