About this file
This document is a standard detail drawing from the United States Department of the Interior's Bureau of Land Management detailing typical road data and road approach specifications. The drawing provides technical diagrams and specifications for road approaches, including plan and profile views with precise dimensional measurements in both English and metric units. Key details include a minimum 50'-0" (15,240 mm) tangent length, a ±30'-0" (9,144 mm) road shoulder radius, and specifications for side slope rounding, cut and fill slopes, and furrow ditches. The drawing emphasizes flexibility in staking and location adjustments, with a note that exact road approach connection locations will be staked in the field. Additional specifications cover slope stakes, reference stakes, and modifications for heavy brush and timber areas, with a safety reminder prominently displayed on the document.
