07 Superelevation Report.zip

This is a Superelevation Report in compressed file format related to road improvement design specifications for the Mojave National Preserve project. The document supports the Federal Highway Administration's invitation for bid on approximately 56.5 miles of road improvements across three primary 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 superelevation report provides technical analysis and design parameters for roadway banking and cross-slope specifications necessary to ensure proper drainage, vehicle safety, and structural integrity on the reconstructed roadways.

The superelevation specifications are critical engineering components for the full depth reclamation and asphalt pavement placement work planned for Kelso-Cima and South Kelbaker Roads, which includes increasing roadway width to 26 feet and realigning select sections. These technical specifications support the overall project scope valued between $80,000,000 and $120,000,000 and are applicable to a full and open competition solicitation with HUBZone price preference. The report ensures compliance with Federal Highway Administration standards and accommodates the natural resource-sensitive construction environment within Mojave National Preserve, where environmental constraints significantly impact construction operations and scheduling.
