About this file

Written by GovTribe AI ·

The document is a Proposed Horizontal & Vertical Alignment Report for MAIN 01, prepared for the Federal Highway Administration's Western Federal Lands Highway Division Project. The report details precise geometric specifications for a road alignment, including comprehensive horizontal and vertical alignment data for a section of roadway designated as MAIN 01. The alignment report provides detailed station-by-station breakdown of horizontal and vertical positioning, with specific measurements including northing and easting coordinates, tangent grades, tangent lengths, and elevation changes across multiple linear and circular elements from station 100+00.000 to 103+40.000. The report includes precise technical specifications such as curve radii, delta angles, and grade percentages, which are critical for road design and construction planning in the Olympic National Park area as part of the ERFO (Emergency Relief for Federally Owned) Repairs 2022 project.
