About this file
These documents are engineering design drawings for the Downstream Guide Wall Silt Removal project at Mississippi River Lock & Dam No. 25, located in Lincoln County, Illinois, under the U.S. Army Corps of Engineers St. Louis District. The technical drawings include multiple detailed site plans, site sections, elevation views, and geological cross-sections depicting proposed rock placement, staged construction approaches, existing and proposed grades, and structural modifications to the downstream guide wall.
The comprehensive set of drawings shows phased rock placement strategies, with multiple stages of graded stone placement, existing intermediate wall configurations, and detailed engineering specifications for wall reconstruction. The project appears focused on silt removal and structural rehabilitation of the downstream guide wall, with precise elevation measurements, geotechnical considerations, and systematic construction sequencing across different sections of the lock and dam infrastructure.
