English: The Aldrich Change Bridge in Aqueduct Park in en:Palmyra, New York.

The bridge was originally built to carry the Erie Canal towpath over a canal weighlock in w:Rochester, New York. It was removed and put into storage in 1879. But in 1880, the wooden change bridge in Palmyra (when the Canal was widened early in its history, there was no room for the south-side towpath through the village, so this bridge was needed to move the towpath to the north side of the canal) collapsed. One span of the Rochester weighlock change bridge was pulled out of storage, shortened, and pressed into service in Palmyra, where it became known as the Aldrich Change Bridge.

When the Barge Canal bypassed the old routing through Palmyra, the change bridge became superfluous. It was purchased by a farmer who used it to bridge Ganargua Creek to access his land. Abandoned in the 1970s or 80s, it was knocked off of its abutments in 1996 by a high icy creek. The Town of Macedon acquired it and moved it to Aqueduct Park in 1998.
