> Starting in 1942, 1,700 miles of military roadway were built over the course of 234 days, connecting eastern British Columbia with Fairbanks, Alaska. Color me dubious on this one. 1700 miles / 234 days = 7.26 miles/day = 0.444 feet/second, every second of every day for about 8 months straight. Even if you had 10 teams working in parallel the entire time, that’s a lot of road.
