Rockland Road

Changing road ID #0892062900 functional class from 5 (Major Collector) to 6 (Minor Collector).
### Description
Lower than expected AADT.  Would like to keep as a collector because historic counts data looks inconsistent.  Can revisit whether this should be local next time.  
### Justification
Need to coordinate with Rockdale County.
