About this file
This vertical alignment review report details the proposed grade changes along a 4-mile section of the Camas Road in Glacier National Park, Montana. The project involves asphalt concrete paving, sub-excavation, slide repair, turnout rehabilitation, curb and gutter, sidewalks, underdrains, ditch reconditioning, and signing and striping. The report provides station elevations and element descriptions for the vertical alignment of the entrance road from the kiosk to the project end, including linear sections, symmetrical parabolas connecting different grades, and corresponding tangent lengths, entrance and exit grades, and middle ordinates. The related federal contract opportunity is being conducted by the Department of Transportation Federal Highway Administration for the MT NPS GLAC 11(3) Camas Road Slumps and Resurface Remaining 4 Miles project.
