Something else I've noticed recently in my research: Carver County's transportation plan, where they propose relocating MN 25 to what is basically the CSAH 33 corridor, with a couple miles of new construction, with a little bit of new construction to tie it directly into the western US 212/MN 5/MN 25 intersection west of NYA.
Just one problem with that. The language for Constitutional Route (C.R.) 25 specifies that it serve both Norwood and Watertown. So while MN 25 could be relocated as the county proposes, MnDOT would still have to retain a state highway that directly connects NYA, Watertown, and Montrose.
This isn't the first time I've seen this sort of disconnect, even within MnDOT. Past versions of MnDOT Metro Division's district plan proposed turning back parts of US 61, MN 20, and MN 50 in Dakota County, even though all three are required to meet Constitutional Route requirements. Especially MN 20, where Constitutional Route 20 is specifically written to end at "a point on Route No 3 in the town(ship) of Douglas, Dakota County, T 113, R 17 W".
