This document is a cross-section drawing set for the Crown Point Trail and Parking Area project prepared by the Federal Highway Administration (FHWA), Office of Federal Lands Highway. The drawings contain engineering cross-sections at multiple survey stations across five distinct project sites: the Parking Lot area (MP 0.00), the Main Trail section MAIN01 (MP 0.95), the Main Trail section MAIN02 (MP 2.40), and two alternate bridge approach sections BAT and BAT2 (both at MP 0.35).

The cross-sections provide detailed elevation profiles, grade information, and subsurface conditions at specific milepost locations. Each cross-section displays design grades, subgrade elevations, and original ground elevations with slope percentages and structural dimensions marked. The drawings show trail and parking surface construction details including fill depths, lane widths, and slope ratios. The project appears to involve trail rehabilitation and parking area improvements in a mountainous terrain with elevation changes ranging from approximately 4,828 to 4,870 feet. The cross-sections include both plan view and profile view representations to convey the three-dimensional design of the constructed surfaces and roadway alignment throughout the project corridor.
