Access roads are classified into several categories based on their intended use and lifespan:
- Permanent Roads– Primary or secondary roads constructed to provide all- or nearly all-season access for silvicultural activities, and are maintained regularly.
- Primary Road– A high specification permanent road which is maintained regularly and serves as a main artery in a network of roads.
- Secondary Road– A permanent road that is maintained periodically, installed for transporting wood products and with a secondary use for other forest activities.
- Temporary Road– A road constructed for a specific use or single operation and normally retired upon completion of the operation.
