About this file
These are engineering plans and specifications for the LD 53 Access Road project in Olmsted, Illinois, prepared by the U.S. Army Corps of Engineers Louisville District. The contract number is W912QR-60440629, with solicitation number 112574 FY2025, and the plans were certified as final in March 2026 with amendments through April 2026.
The project involves demolition and reconstruction of approximately 1,250 linear feet of access road with an average width of 20 feet. Key work requirements include: removing existing pavement at full depth in designated areas; exposing and covering a culvert 3 feet on either side of a sinkhole with AASHTO Class 2 non-woven geotextile fabric, then backfilling with No. 57 stone; constructing proposed asphalt pavement patches and full-depth replacements with specifications for 1.5" asphalt surface, 2" asphalt base, and 8" aggregate base course; implementing temporary and permanent erosion and sediment controls per Illinois Urban Manual standards; and maintaining resident access at all times with a minimum 14-day advance notification requirement. The contractor must coordinate with the Contracting Officer's Representative, verify all existing utilities prior to construction, coordinate road shutdowns with local county agencies, and inspect and immediately remove soil, gravel, debris, and spills from public roads and driveways. All disturbed earth areas not receiving pavement or rock surfacing must be seeded and straw-covered.
