Whitehorse Creek Crossing

The road segment from milepost 69.5 to milepost 69.7 is referred to as Whitehorse Crossing. The road gains elevation over a small hill on the west side of a curve. For travelers heading east (toward the lake), the gain in elevation is enough to create a visual barrier of the upcoming (blind) curve. Park staff have reported accidents occurring in this area (Toso pers. comm. 2002). This alternative would reduce the profile of the hill (flatten the road) to increase sight distance, raise the super-elevation of the curve (raise the outside of the curve) to help keep vehicles in the roadway, improve the horizontal alignment for safety, and provide additional signage (figure 4).

Cut and fill slopes in this area would be 2:1. This would keep new disturbance to a minimum, avoid snags (dead trees used by wildlife species as habitat) and large trees, and prevent the placement of fill into the ephemeral Whitehorse Creek.
