Castleton Bridge

The Castleton Bridge is a cantilever truss bridge over the Hudson River, connecting Coeymans, Albany County with Schodack, Rensselaer County in New York. It carries the Berkshire Connector of the New York State Thruway. This bridge is also sometimes called the Castleton-on-Hudson Bridge and is situated in close proximity to the Alfred H. Smith Memorial Bridge, which is used by rail traffic.

The Castleton Bridge is located on the longest section of the New York State Thruway that does not have an Interstate Highway designation, between exits 21A and B1. There is a $0.62 toll each way to cross this bridge. It is not collected at a separate toll barrier, but is rather collected as part of the Thruway's closed toll system. It costs at least $1.05 to cross, by traveling between exits 22 and B1 on the Thruway. It is the northernmost road bridge on the Hudson River with a toll and is the only bridge with a toll in both directions; every road bridge south of this has an eastbound-only toll.
