US 89 and 91 have several waypoints in the Logan area that should probably be renamed because they refer to routes that do not exist anymore:
UT238 on both 89 and 91 should just become 300 South
UT288 on 89 should become 1200 East
UT239 on 91 should become 1400 North
UT237 on 91 should become Hyde Park Lane
