The Navajo Division of Transportation is seeking a qualified contractor to perform full road‑improvement work on the N8066 corridor (approximately 6.92 mi) in the Black Mesa area of the Navajo Nation. The scope includes earthwork, subgrade stabilization, aggregate base placement, asphalt paving, drainage structures (including precast concrete arch culverts), fencing, cattle‑guards, gates, signage, pavement markings, erosion control, waterline installation, and temporary traffic control.
