About this file
This horizontal alignment review report summarizes the design of a proposed road rehabilitation project for East Rim Drive within Crater Lake National Park in Oregon. The report details the alignment geometry including linear segments, circular curves, radii, lengths, and tangents. It analyzes the horizontal geometry from station 1000.000 to station 2796.513 including 21 elements consisting of lines and curves. Key information provided includes radii ranging from 25 to 300 feet, curve deltas from 2.865 to 130.684 degrees, and total alignment length of 2796.513 feet. This document appears to be a technical design review for the proposed road rehabilitation project.
