Sequential numbers along the Adirondack Northway omit Exit 3 between New York Route 5 (Exit 2) and New York Route 155 (Exit 4). The southernmost portion of the Northway opened in 1960 and Exit 3 was reserved for the planned interchange with the Northway-Northside Connection.2,3
The proposed Northway-Northside Connection was numbered as Interstate 687 by 1967 and construction began at the south end (Exit 5A on I-90) by 1971. Changes in the State and Federal funding programs2 and increasing community opposition1,3 however led to the removal of the planned freeway from the Capital District’s long range highway plan in 1973. I-687 was subsequently dropped from the national interstate system plan in 1977.2,3
The Corporate Woods interchange remains as the lone piece of infrastructure built for I-687.1 It provides a high speed entrance to a 30 mile per hour arterial through Corporate Woods business park.
