Amendment A001.pdf

This is an amendment to a federal solicitation for road improvement work within Mojave National Preserve. The underlying solicitation (6982AF25B000013) is an Invitation for Bid issued by the Federal Highway Administration, Central Federal Lands Highway Division, in coordination with the National Park Service. The project encompasses approximately 56.5 miles of road improvements across three main routes: Kelso-Cima Road (19.3 miles), South Kelbaker Road (22.3 miles), and Morningstar Mine Road (14.9 miles) in San Bernardino County, California.

The scope of work includes full depth reclamation and resurfacing of existing pavements, roadway widening to a consistent 26 feet, minor horizontal and vertical realignment in select areas, reinforcement of 48 low water crossings, and safety improvements including rumble strips, signing, pavement markings, and paved pullouts. The estimated project cost ranges from $80,000,000 to $120,000,000. The solicitation is structured as a full and open competition with HUBZone price preference. Given the natural resource sensitivity of the project location and associated environmental constraints, the work requires careful attention to construction quality, traffic control, visitor relations, and adherence to an environmentally-constrained construction schedule. Specific details regarding the amendment's modifications, response deadlines, and award dates are not provided in the available file excerpt.
