sentences:  One possible routing for an "east-west freeway" would travel due west from Interstate 95 near Waterville, following the U.S. Route 2 corridor through Maine, New Hampshire, Vermont, and upper New York state.The more northerly-located link to Québec would exist with Autoroute 73, whose "Chaudière-Appalaches" proposed southeast extension within Quebec could link through, and generally heads directly towards (as Quebec Route 173 already does), the existing Armstrong–Jackman Border Crossing some 57 km (34 miles) northeast of Coburn Gore, ME, despite no link to the American Interstate Highway System existing or planned to exist to it — only the two-lane U.S. Route 201 - Maine State Route 6 currently has a northern terminus at that specific port of entry.The only existing mainline freeway link on both sides of the border between any part of New England and Canada that does not become a two-way road within any close proximity of the crossing is the north-south linkup at the Derby Line–Rock Island Border Crossing, between Interstate 91 in Vermont and Quebec Autoroute 55.
