https://fox59.com/news/interchange-at-96th-and-keystone-opens-after-3-years-of-construction/The Keystone Pkwy/96th St interchange opened in December 2019, replacing the stoplight, so does that warrant Keystone getting extended down to I-465 in usaf?

https://www.953mnc.com/2016/02/05/933-to-south-bend/In Downtown South Bend, the one-way pair of Michigan/St Joseph and Main Streets carrying IN 933 and BUS US 31 are now both two-way streets. The routes now run only on Main St. between Marion and Sample Streets. This necessitates the moving of the IN23_S and US20Bus waypoints on IN 933, the IN23/933 and US20Bus waypoints on BUS US 31, the US31Bus waypoint on BUS US 20, and the IN933_N waypoint on IN 23.
3) US 6 in Marshall County: When the new US 31 freeway was opened, they waypoint for US 31 got moved correctly, but no waypoint was put in at the stoplight at Old US 31/Michigan Rd. Also in Marshall County, I don't know what, if any, criteria there are for putting waypoints at non-highway intersections, but Plymouth-Goshen Trail is a frequent turn-off for traffic going between Plymouth/Bremen and Elkhart/Goshen.
4) IN 931 in St. Joseph County: The southern terminus is correctly labeled as SJo/Mar but on the map the point is a fair amount off from the County Line.
5) US 12 in Porter County: The waypoint for IN 49 is on the road overpass instead of the interchange which is a bit to the west.
