The Aldrich Change Bridge, built in 1858, is the oldest cast and wrought iron bridge in New York. Manufactured in Waterford, NY by John Hutchinson, the bridge was based on the design of a prominent iron-truss bridge engineer of the mid-1800s, Squire Whipple, also known as the “father of iron bridge building in America.”  

The bridge was originally located at a weigh lock station in Rochester. In 1880, the bridge was relocated to the Macedon-Palmyra town line. Named Bridge No. 35 the structure was also called the Sexton Bridge after early area businessman, Pliny T. Sexton. A farmer by the name of Aldrich owned land and a home on the east side of the bridge, and hence the bridge became known as the Aldrich Change Bridge. 

Following the construction of the NYS Barge Canal in 1905, by 1913, the spur through Palmyra was recommended to be closed. The Aldrich Change Bridge was removed and sold for $100 to George B. Lent, who moved the bridge to his farm between Macedon and Palmyra, placing it across Ganargua Creek so he had access to both sides of his property along the creek. By the late 1960s, the bridge was abandoned. During a storm in the 1990s, the bridge was washed from its abutments. In 1996, the town of Macedon obtained ownership of the bridge and moved it to the Macedon Town Highway Department to store. 

A Historic American Engineering Record review of the bridge was conducted in 1996.  Following the extensive study, the Aldrich Change Bridge was refurbished and in 1997 was installed in the  Macedon-Palmyra Aqueduct Park upon new abutments constructed from old canal stones.
