ALTERNATIVE B: RESURFACING, RESTORATION, AND REHABILITATION

Roadway

This alternative refers to resurfacing, restoration, and rehabilitation of the existing roadway starting at milepost 65.5, the western boundary of the park, and ending at milepost 73.2, just west of Annie Springs Junction. It is intended to improve poor pavement conditions, restore adequate drainage, and improve sight distances. New traffic control and informational signage would be installed. The road would be improved within the existing road alignment; no widening would take place. It would include recycling a portion of the existing roadway surface and base; laying, leveling, and compacting this material; and applying a 3-inch asphaltic concrete overlay. Subexcavation of unsuitable sub-grade material and backfill with free-draining sub-base would be performed, as necessary.

Guardrails would be maintained, replaced, or added as determined necessary for safety. Guardrails not needed would be removed and stored, if in good condition, by the park for reuse at another location. Culverts that are partially plugged would be cleaned to improve drainage. Cuts and fill slopes would be between 1.5:1 (1 foot vertical rise to 1.5 feet of horizontal run) and 2:1 (1 foot vertical rise to 2 feet of horizontal run).

Topsoil and forest duff from the project site would be salvaged and stored to restore areas of disturbance. The storage would be within the existing Highway 62 West corridor or at designated staging sites on previously disturbed ground.
