The only revision I would make here at this point would be to remove the "5th/6thAve" point on both US 31 and US 280 completely (visible and hidden). 1PPI should be enough to cover both here in my opinion.
Other Point Concerns for US 31/US 280 in area:
US 31:
1. CarrBlvd>-CarBlvd_S (I think)
2. UnivBlvd>-UniBlvd.
3. BroMedCenDr needs to be shortened.
4. Maybe replace the shaping point south of CanRd with a visible point.
US 280:
1. UnivBlvd>-UniBlvd.
2. CherRd>-CheRd.
3. I-459(19)>-I-459.
