Would recommend two points be added to the route.
1)
Church Road. Why? Before the construction* of North Chapel Drive on the other side of US-19, Church Road WAS the main connection to US-19 for both directions. Plus, they recently added a traffic light there (upgraded from 4-way Stop signs), and it still provides the most used access to SB US-19 there.
2)
Pearce Mill Road. Why? Major connection down into North Park.
