I did this circle route for my trip to the old homestead. Did a ferry ride and rim of Lake Superior camping trip on the way to Manitoba and bag drove the three 8 hour plus days through the States and Sudbury.
I thought the 17 around the lake was pretty good. Lots of newly paved sections and passing lanes and very little truck traffic (due to the 11 being the preferred trucker route). Camping was excellent. There was a big rerouting project going on east of Dryden. I was wondering if they would twin the part they were working on because it would make sense to do it now while all the equipment is there. It seemed like there was enough clearing to make that happen. Was very happy to see the prairies though, unlike many Canadians, the Canadian Shield and endless pine trees quickly loses its appeal to me.
Once again Manitoba wins the award hands down for the worst highways in Canada. Roads designed for pick-up or 1 ton grain trucks are nowhere near adequate for the B-train grain trucks and livestock liners that roar down these roads at 100km per hour. The roads are pounded to shit and there seems to be no appetite to do what's required to fix the problem.
Heading back through the States was pretty good but there are sections in the UP that need to be improved.
Re-entered Canada at SSM was held up 4 times for paving, culvert replacement and blasting (somewhere between the Espanola turnoff and Sudbury). Between North Bay and Arnprior I was wondering if I was ever going to get on 4 lanes again!
Overall the driving experience wasn't too bad, but I wish both level of governments would just pick a route and get the hell going with improving the highway to a 4 lane standard.
cheers!
