usaush: United States Historic US Routes

[shiggins]

The new Old US 61 in Minnesota continues beyond the northern terminus of the route si404 drafted. Old US 61 turns east onto MN 210 toward Carlton. There aren't any Old US 61 shields on MN 45, but they reappear on CR 61 east of Scanlon. Before reaching I-35, the route then jumps north just before reaching exit 245 on I-35. This may be the northern terminus, as I haven't found any shields in St Louis County.

Also, the route as drafted is missing a point at MN23_W.
