Editing U.S. Route 9 (section)

==History==
Prior to the opening of the Cape May–Lewes Ferry in 1964, US&nbsp;9 ended on Lafayette Street in [[Cape May, New Jersey]]. It was rerouted to the west, via Sandman Boulevard and Lincoln Avenues, to meet the new ferry, and its southern stub into Cape May was renumbered as [[New Jersey Route 109|Route&nbsp;109]].<ref name=endpoints>{{cite web |last = Sanderson |first = Dale |publication-date = August 17, 2009 |title = Endpoints of US Highways: US 9 |work = US Ends.com |url = http://usends.com/9.html |access-date = January 3, 2012 }}{{sps|certain=yes|date=July 2024}}</ref>

Originally, the road continued north across the border (as Route&nbsp;9 toward [[Montreal]]) through the customs facilities now used by [[Interstate 87 (New York)|I-87]]/[[Quebec Autoroute 15|Autoroute&nbsp;15]]. The official northern terminus (the point where the "End US&nbsp;9" sign is posted) is just south of the interchange with I-87, less than {{One2a|{{convert|1|mi|km|spell=in}}}} from customs. The old Route 9 continues north for a very short distance (0.46 m/0.74&nbsp;km) as the unsigned New York State Route 971B (NY 971B), which ends in a cul-de-sac just short of the Canadian border.
