Drove over it today. Can confirm that the current reality on the ground matches what OSM shows in terms of where the new roadways are. Changes are needed to the following routes.
MN 36: removed from downtown Stillwater, routed onto the new bridge
MN 95: has not moved, but no longer has a concurrency with MN 36, so points will need renaming
WI 64: moved onto new bridge and approach
WI 35: rerouted east on new roadway south of Houlton, joins WI 64 at new interchange
The former routings of WI 35 and WI 64 through Houlton are no longer numbered state highways. Likewise for Chestnut St East on the Minnesota side. The old bridge is closed to traffic, and I believe this is intended to be permanent.
