This is a major road improvement project for approximately 56.5 miles within the Mojave National Preserve in San Bernardino County, California, with an estimated budget between $80 million and $120 million. The work involves resurfacing, restoration, and rehabilitation on three roads, including full-depth reclamation, new pavement, roadway widening, safety improvements, and reinforcing numerous low-water crossings. The anticipated construction start is early to mid-2026, with an estimated duration of 24 to 30 months. The project is in a natural resource-sensitive area with environmental constraints that will impact the schedule and operations. Prior experience on projects of similar magnitude is required.
