The Collar City Bridge (also known as the Hoosick Street Bridge) carries NY 7 across the Hudson River connecting Colonie, New York with Troy, by way of passing over Green Island. As the Northern Terminus of Interstate 787 is unclear, it may share a concurrency with NY 7 across the bridge. 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 Route 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.
