01 Horizontal and Vertical Alignment Listings.zip

This file is a compressed archive containing horizontal and vertical alignment listings for a road improvement project.

The archive supports the solicitation for improvements to approximately 56.5 miles of roads within Mojave National Preserve in San Bernardino County, California. The project encompasses work on Kelso-Cima Road (19.3 miles), South Kelbaker Road (22.3 miles), and Morningstar Mine Road (14.9 miles). The alignment listings document the horizontal and vertical design parameters for these roadway segments, which are essential technical specifications for bidders to understand the scope of reconstruction and rehabilitation work. The improvements include full depth reclamation and new asphalt placement, roadway widening to 26 feet, minor horizontal and vertical realignment in select areas, reinforcement of 48 low water crossings, and safety enhancements including rumble strips, signing, pavement markings, and paved pullouts. The Federal Highway Administration, Central Federal Lands Highway Division, in coordination with the National Park Service, is conducting this invitation for bid under full and open competition with HUBZone price preference. The estimated project cost ranges from $80,000,000 to $120,000,000, with work subject to environmental constraints due to the natural resource sensitive area designation. These alignment documents serve as critical technical references for contractors to prepare accurate bids and construction plans.
