For a time, plans called for the Sunrise Highway to skirt along the edge of the cliffs leading down to the desert via Kwaaymii Road. This idea was abandoned due to the narrow right of way and extensive rocks that fell from the cliffs above. This picture shows the northernmost section of the abandoned Sunrise Highway as seen looking south. 06/22/04
A retaining wall was considered for supporting the proposed highway, and a portion of it remains in place along an abandoned stretch of road. 06/22/04
