US 61:
1. Consider replacing the shaping point between MO168_S and US24_W with a visible point.
2.  Is MOsN_Mar correct?  (also affects (Great River Road (Canton))
3.  ERossSt>-RossSt (also affects US 24)

MO 168: Consider replacing the shaping point west of US61 with a visible point.

Great River Road (St Louis): I-72(152)>-I-72(157)

Unrelated to the ones above, but I saw a shaping point on MO5BusCam between US54 and MO5_N that needs to be relocated and/or replaced by a visible point.

I did not start the Great River Road files nor have I worked on them. I need clarity on their maintenance. I am happy to take them over and probably should, but I did not have a role in their creation.
