The Collar City Bridge (also known as the Hoosick Street Bridge) carries NYS Route 7 (NY 7) across the Hudson River connecting Colonie, New York, with Troy, by way of passing over Green Island.
The bridge had been planned since the 1950s, but did not open to traffic until 1981 connecting Troy and Green Island to I-787. By the end of the decade, the NY 7 Freeway was completed with a connection to the bridge. The bridge's official name, a reference to the City of Troy's nickname, was selected by an elderly couple in nearby Berlin.[1]
