Thaddeus Kosciusko Bridge
Thaddeus Kosciusko Bridge, Twin arch bridges on Interstate 87 in Halfmoon, United States.
Two identical steel bridges span the Mohawk River with three lanes in each direction, connecting Colonie in Albany County to Halfmoon in Saratoga County.
The bridges opened in 1959 as part of the Adirondack Northway project, and Governor Nelson Rockefeller formally inaugurated the Interstate 87 section in May 1961.
The bridges honor General Tadeusz Kościuszko, who served in the American Revolutionary War from 1776 to 1784 before returning to fight for Poland.
The bridge decks underwent complete replacement in 2013 using lightweight precast concrete pieces, which reduced the weight of each section by twenty-six percent.
The structure accommodates approximately 115,000 vehicles each weekday, making it a central transportation artery in New York State's Capital District.
