This bridge has been demolished and replaced!

The state of New York, like neighboring Pennsylvania, continued to rely on the metal truss bridge into the first third of the 20th Century, developing a standard plan for metal truss bridges and building them with moderate frequency. Unlike Pennsylvania, which went with the Pratt and Parker truss configurations, New York engineers instead went with the Warren and Warren Polygonal truss configurations. A number of these structures survive today in New York. They all feature riveted connections and "massive" members and have what would have been at the time a relatively wide deck width. Today in the 21st century, the continuity from the standard plan design is psychologically enhanced by the fact that nearly all of these bridges in New York are painted in the same green color. Despite the fact that they are late examples of truss bridge construction, and a relatively fair number remain, they still represent a structure type no longer built today, and are also highly attractive structures that make crossing a bridge something to notice and enjoy. They are also, if properly maintained, strong bridges that are more than capable of serving modern traffic needs safely and efficiently. For all these reasons, the maintenance and preservation of these structures makes sense for fiscal reasons, but also for the greater purpose of preserving these attractive structures, which offer a window into past forms of fabrication, construction, and engineering.

The CR-16 is a great example of this trend. It also features a through plate girder approach span at each end. New York also had a standard plan for plate girder bridges, and these approach spans appear to be built to the plan. An interpretive plaque on the bridge, likely placed when this bridge was built, mentions this crossing was where the first Genesee River Bridge built in the county was constructed, which was in 1809.
