The bridge carries Interstate 90, in the east-west direction, over the Hudson River between Albany and Rensselaer Counties. 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 to be between $80 and $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 percent estimated traffic growth during the life of the bridge. The bridge's design is similar to that of the Interstate 35W bridge in Minneapolis, MN, which collapsed during rush hour on August 1, 2007. This realization by New York State transportation officials prompted full-scale inspections of the state's major highway bridges, including the Patroon Island Bridge. Subsequently, the bridge was deemed safe for the time being, but would need substantial repairs and retrofitting in order to ensure motorist safety, and to extend its useful service life if replacement was found not to be a viable option in the near future.{{citation needed|date=March 2013}} On May 31, 2016, the New York State Department of Transportation declared that it had completed a $148-million-dollar renovation and rebuild of the bridge. The bridge's name comes from the former (Lower) Patroon Island that once existed adjacent to the bridge. A patroon was a proprietor of a tract of land in the 17th-century Dutch colony of New Netherland in North America. See also{{portal|Bridges|New York}}
