About this file
This document is a set of plans related to a federal construction contract opportunity for channel improvement and closure work on the Mississippi River. The contract solicitation number is W912EE24B0002 and is being issued by the Department of the Army Corps of Engineers Vicksburg District. The plans depict the design and typical sections for installing 3 feet of #57 gravel and "C" stone paving to construct a 10 foot wide road, excavating an area to grade for the closure, and building a rock chute transition. Notes provide additional details such as horizontal and vertical coordinate systems, control line data location, survey dates, and instructions for spreading excess degraded sand.
