The Patroon Island Bridge is a major crossing of the Hudson River in Albany, New York. The bridge carries Interstate 90, in the east-west direction, over the Hudson River between Albany and Rensselaer County, New York. It has been in service since 1968; however, some structural repairs were made in 1992. The bridge consists of ten spans. Seven spans are considered the main spans and consist of steel trusses and concrete decks. The other three spans are considered approach spans, which are supported by plate girders. The main span over the river-shipping channel is convert|375|ft|m long and convert|89|ft|m wide, and the overall bridge length is convert|1795|ft|m. There is an estimated convert|60|ft|m of clearance for shipping on the Hudson River below, which changes with the local tide. Today's replacement cost is estimated at $80 - 100 million. The bridge has an HS Inventory load rating of 35 tons, and is inspected annually. The average daily traffic count was 70,787 in 1998 with a 4.5% estimated traffic growth during the life of the bridge.

The bridge's name comes from the former (Lower) Patroon Island that once existed adjacent to the bridge. (This maps shows location of in North America.)
