About this file
These are cross-section engineering drawings for the Upper Mississippi River Navigation Ecosystem Sustainability Project (NESP), specifically for Lock and Dam No. 25 located in the St. Louis District. The detailed technical drawings, prepared by the U.S. Army Corps of Engineers, illustrate foundation preparation, riprap excavation, and separator wall installation across multiple station points from 0+00 to 14+00.
The drawings provide comprehensive technical specifications for a complex river infrastructure project, including excavation phases, riprap placement, sand fill grading, and wall embedment. Key technical details include a separator wall with a 20-foot embedment depth, a top elevation of 433.6' NAVD88, and specific requirements for riprap and sand backfill placement in controlled lifts. The project involves careful excavation around existing timber cribbing, intermediate walls, and riprap, with precise elevation and slope specifications to ensure structural integrity and scour protection.
