The northbound and the southbound spans each carry three lanes of Interstate 87 between exits 7 and 8.

The toll-free bridge opened in 1959 as part of the Adirondack Northway, a 176-mile (283 km) highway linking Albany and the Canada–United States border at Champlain.

The Interstate 87 section of the highway was formally inaugurated by Governor Nelson Rockefeller on May 26, 1961.

[1] The bridge is named (using an anglicized form) in honor of Tadeusz Kościuszko (1746–1817), the preeminent national figure in Poland's fight for independence.

Kościuszko arrived in Colonial America a month after the July 4, 1776 Declaration of Independence and remained a notable military leader throughout the Revolutionary War, attaining the rank of general as well as honorary American citizenship.
