Route 217 previously extended south from Montée Guay to the Canada–US border, connecting with Meridian Road at Champlain, New York. However, this port of entry closed around 1950, with the Canada border station later dismantled and the US border station converted into offices for the United States Department of Agriculture. This 1.2km (1mi) segment remained part of Route 217 (and its pre-1970s predecessor, Route 9A) as recent as 2005, but in recent years has been truncated at Montée Guay.
