About this file

This document contains preliminary engineering plan sheets for a Federal Lands Highway emergency road repair project located near Concrete, Washington. The project involves repairing Forest Road 11 at Mile Post 23.9, with a project length of 0.038 miles and an estimated cost between $700,000 and $2,000,000. The technical drawings include detailed specifications for critical construction elements such as stabilized construction exits, check dam installations for erosion control, temporary stream diversion methods, and survey control point coordinates. The project is sponsored by the Department of Transportation Federal Highway Administration and is tentatively scheduled for solicitation in Winter/Spring 2025, with a projected completion date in Fall 2026. The repair work will include subexcavation, aggregate surfacing, and root-wad/riprap embankment stabilization in Whatcom County, Washington.
