About this file
This document is a set of construction drawings for a federal contract opportunity issued by the U.S. Army Corps of Engineers, Rock Island District, for road repaving work at Thompson Causeway Recreation Area in Thompson, Illinois, located within the Mississippi River Basin. The project, identified as River Birch Road Repaving, involves demolition and reconstruction of an existing asphalt road surface. The drawings are dated March 2026 and include a cover sheet, index of sheets, site map, general notes, demolition plan and sections, and new work plan and sections.
The scope of work includes milling and removal of 4 inches of existing asphalt pavement and excavating existing aggregate base and subgrade to a depth of 12 inches, with stockpiling of materials for reuse. New work consists of placing 8 inches of stockpiled asphalt and base millings on the existing aggregate base, topped with 4 inches of new asphalt pavement in a binder course and surface course configuration. The road width is approximately 27 feet 8 inches with shoulders widened from 13 to 16 feet on the north side. Work must comply with all federal, state, and local construction laws and ordinances, require coordination with the Government on parking and staging areas, utility locations, and existing site features that must remain undisturbed, including three bollards, a chain gate with posts, and existing riprap. The contractor must field-verify existing conditions and dimensions prior to work commencement.
