02-May-2002 -- As I explained at 46N 83W, I was only able to scout a few not yet visited confluences from the main highway during our 4,000 km trip from Halifax, NS to Winnipeg, MB. This was because our car was heavily loaded with our clothes and other personal items; and we had SNOW on April 26, April 28 and May 2 – this was not supposed to happen during our trip, but this is Canada!
The snow that had fallen overnight last night apparently was bad enough that it caused three semi-trailer accidents between Kenora and Dryden on the Trans-Canada highway, closing it for most of the day. This was the route we had to travel to Winnipeg (except for a detour around the accident sites down to Fort Frances on the US border and back up to Kenora, which would be about 270 km longer, and on narrower roads.) I stopped in Dryden, where the local Ontario Provincial Police detachment told me that the highway was now open - the radio station did not have current information.
I also asked the OPP about trying to get into the vicinity of the 50N 93W confluence. Although there is a small provincial road (605) up past the community of Eton-Rugby (see the Mapquest maps), the officer indicated that a 4WD would be necessary to get much further. (Mapquest seems to show that you can get closer if you go up road 665, then west through Amesdale.)
