The Oneil Road Bridge is a closed circa 1913 Baltimore through truss over the Seneca River on Oneil Road in Cayuga County, New York.
The Erie Canal was being enlarged to accommodate larger barges powered by engines instead of mules in the early 1900s. 1 A vote in 1903 resulted in the alignment of the canal being shifted in Cayuga County. Instead of flowing through the towns of Weedsport, Port Byron, and Montezuma, the realigned canal would follow the Seneca River. Work began on the relocated canal 1908 and was completed in 1913, which included the construction of a bridge for Oneil Road.
