About this file
This is a Horizontal Alignment Review Report detailing the physical data and proposed alignment specifications for the Sportsman's Park Transportation Improvements project (ID BOR SRAO 0017(1)) issued by the U.S. Department of Transportation Federal Highway Administration's Western Federal Lands Highway Division in Vancouver, Washington.
The report provides detailed technical specifications for the main alignment (MAIN_01) covering stations 10+00.00 to 24+59.89, including precise measurements for linear and circular elements. The alignment consists of multiple segments with specific parameters such as coordinates (Northing/Easting), radii, delta angles, chord lengths, and tangential directions. Key features include various curve elements ranging from 60-foot to 1,200-foot radii, with the largest curved section being 161.147 feet in length with a 7.694° left delta angle. The document includes detailed station points, geometric calculations, and directional bearings for each segment of the proposed roadway alignment.
