This is a zipped file containing wilderness boundary documentation related to a federal road improvement project in Mojave National Preserve. The file supports an Invitation for Bid (IFB) solicitation numbered 6982AF25B000013 issued by the Federal Highway Administration, Central Federal Lands Highway Division (FHWA-CFLHD) in coordination with the National Park Service for improvements to approximately 56.5 miles of roads within the preserve located in San Bernardino County, California.

The project encompasses road improvements on three main routes: Kelso-Cima Road (19.3 miles), South Kelbaker Road (22.3 miles), and Morningstar Mine Road (14.9 miles). Work includes full-depth reclamation and new asphalt pavement placement with roadway widening to 26 feet, reinforcement of 48 low-water crossings (11 on South Kelbaker and 37 on Kelso-Cima), and safety enhancements including rumble strips, signage, pavement markings, and paved pullouts. The Morningstar Mine Road work consists of full-depth reclamation with surface-course aggregate placement. The estimated project cost ranges from $80,000,000 to $120,000,000. The procurement is designated as full and open competition with HUBZone price preference. Work occurs in a natural resource sensitive area with environmental constraints affecting construction schedules and operations, requiring attention to detail in road construction, traffic control, visitor relations, and timely project completion.
