ROAD 500
High Priority Main Line Road
Mileage begins at the end of the pavement (Forest Office) and proceeds southeast to the junction
of Road 540.
Site 1: Mile 0.0 to 0.25 (Jct. Rd. 520) (1320 ft.)
Priority: High
This section of road is insloped with an outside berm and inboard ditch. Although originally
designed as an all-weather permanent rocked road, the running surface has eroded to native
material or bedrock in many places with numerous potholes. At mile 0.1, there is an active spring
on the cutbank and in the inboard ditch. The ditch and culvert at this location should be
maintained. Outside berm is largely non-existent.
Remedial treatments include:
1. Outslope road
2. Apply a 3 inch layer of 2 inch – minus crushed rock to the running surface.
3. Install rocked rolling dips
4. Excavate outside berm and smooth over roadway
5. Armor outfalls
6. Retain and improve inboard ditch at mile 0.1
Site 2: Mile 0.25 (Jct. Rd. 520) to 0.9 (3432 ft.)
