Having a coast to coast Highway would go a long way toward a National Highway System. Speaking of: does anyone think there will be a fixed-link freeway from Vancouver to Halifax by the end of the century? There are already some movements toward that: Autoroute 85 soon will close the gap between Quebec and the Atlantic Provinces. Ontario is building Route 400 toward Sudbury. British Columbia plans on twinning Route 1 to close to Alberta by 2050. That leaves Alberta to Ontario, which is a huge gap (2,263 miles). But there are some big cities along there, including Calgary and Winnipeg. Winnipeg to Sudbury is the biggest hurdle, at 1,000 miles with few big cities. On the upside for feasibility, Ontario is the most populated province, although they’re mostly focused on the Windsor to Ottawa corridor. After all, half of Canada lives between Windsor and Quebec City.
What do you think?
Full freeway will probably not happen for the Ontario stretch. Why they are even extending Hwy 400 from Toronto to Sudbury was really just political lobbying, since full-controlled access isn't really necessary for that stretch.
