About this file
This is a Physical Data document showing the vertical alignment review report for a Federal Highway Administration road construction project at Sportsman's Park. The document details the technical specifications for road grading and elevation changes along alignment W1700SRD, which runs from station 1+00.00 to 2+39.39.
The alignment begins at elevation 4368.241 feet and includes multiple linear and symmetrical parabola elements with varying grades between -0.026 and -0.043. Key components include a 62-foot linear section, followed by a 16-foot symmetrical parabola, a 28-foot linear section, a 24-foot symmetrical parabola, and ending with a 9.393-foot linear section at elevation 4363.335 feet. The document includes detailed calculations for entrance/exit grades, K values, and middle ordinates for each parabolic curve section. This technical data would be used by contractors to properly construct the road grade for this transportation improvement project.
