From east to west:
1. The 13 point for I-290 needs to be added to the MA 122A file and synced to it.
2. I would also consider recentering the 12 point on I-290 for MA 146.
3. I would think the 9 point would be between Swanson St and Auburn St based on there being half interchanges without 0.5 mile spacing and any routes being mapped.
4. Part of me wanted to consider a graph connection with MA 12 at the 8 point, but I cannot be on board with it since it is signed as
Exit 7.
