About this file
This is a horizontal alignment review report detailing the proposed geometric design specifications for the Sportsman's Park Transportation Improvements project (ID BOR SRAO 0017(1)) managed by the U.S. Department of Transportation Federal Highway Administration's Western Federal Lands Highway Division in Vancouver, Washington.
The alignment, designated as "OVERLOOK," spans from station 3+00.00 to 3+58.38 and consists of a series of linear and circular elements. The geometric design includes specific coordinates (northing and easting), with key measurements including a 10-foot radius curve with a 35.679° right turn, followed by a 40.113-foot tangent section, and ending with a 50-foot radius curve with a 6.473° left turn. The report provides detailed technical specifications including tangential directions, chord lengths, middle ordinates, and external measurements for each curve element. All measurements are provided in feet and the design was last revised on October 17, 2024.
