eastward through Vermont and New Hampshire. The Federal Highway Administration ultimately did not approve these plans. Northern New England is served by three north–south freeways radiating from Boston and by Interstate 91, which follows the Connecticut River. However, the northernmost complete east–west freeway in the region, Interstate 90 in Massachusetts, does not enter northern New England. East–west travel through northern New England is facilitated by three freeway segments: Interstate 89 between Montpelier, Vermont, and Burlington. US 4 west of Rutland, Vermont. New Hampshire Route 101 from Manchester, New Hampshire, eastward to the ocean. Maine Senator Olympia Snowe said in 2004 that the region is disadvantaged by the fact that it was the only region in the US for which a federal High Priority Corridor was not designated in the 1991 Intermodal Surface Transportation Efficiency Act. In 2012, the east–west highway was again proposed, this time as a privately financed toll road. Current backers of the highway propose an east–west axis through northern and central Maine, with three potential freeway links with Canada—two from Québec, and one from New Brunswick. One portion of the new highway would run from Interstate 395 in Brewer, Maine, to the Canadian border near Calais, with a direct link to New Brunswick Route 1, a major transportation corridor serving the Maritimes. A second would travel northwest from Interstate 95 near Waterville, Maine, to the Canadian border at Coburn Gore, with a connection to a proposed extension of Quebec Autoroute 10 toward Montreal. A third would travel due west from I-95 near Waterville, following the U.S. Route 2 corridor through Maine, New Hampshire, Vermont, and northern New York, with Quebec's Autoroute 73 having a southeasterly oriented southern end that heads for the Armstrong-Jackman Border Crossing, as Quebec Route 173 already reaches the United States at the same port of entry. Interstate 98 As originally proposed by the Michigan State Highway Department in 1958, I-696 would have been numbered Interstate 98. Since then, another highway in Upstate New York and Vermont has been linked to the number. Plans for the Rooftop Highway, a proposed limited-access highway that would extend for from Watertown, New York, to Swanton, Vermont, which I-89 travels through (at exit 21), first surfaced in the 1950s. If built, the highway would likely follow the US 11 corridor across the northern part of New York's North Country, connecting I-81 to I-89. A study called the North
