ALTERNATIVE B: RESURFACING, RESTORATION, AND REHABILITATION
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.
