Routing
Interstate 990, the highest-numbered Interstate highway, is metropolitan Buffalo's Northeast Expressway. The purpose of the freeway is to serve the greater Buffalo area with access to the State University of Buffalo and the city of Lockport. The northern terminus was to have been further northeast, but plans for an extension have yet been stymied.
History
On April 17, 1993, AASHTO approved the extension of Interstate 990 from New York 299 (North French Road) northeast to New York 263 (Millersport Highway).
It is rumored that Interstate 990 was a part of a 1960s/70s plan of an Niagara Falls to Rochester freeway. Interstate 990 may have been planned to tie into this route or act as its westernmost segment. New York 531 from Gates westward to Brockport most likely is a result of this initial idea.
