Vermillion-Newcastle Bridge Hydrographic Survey Project

near Vermillion, South Dakota

Eisenbraun and Associates has made important contributions to many high profile civil engineering projects. One such project involved working with several other parties to accomplish spanning the Missouri River with a new bridge near Vermillion, South Dakota. Banner and Associates along with CH2M Hill contracted with the South Dakota Department of Transportation and the Nebraska Department of Roads for design of roadway and bridge crossings over the Missouri and Vermillion Rivers from Vermillion, South Dakota to Newcastle, Nebraska. Eisenbraun and Associates provided hydrographic survey services on the Missouri and Vermillion Rivers for the proposed bridge crossing. Work included providing cross-sections on the Missouri River 1000-foot upstream and downstream of the proposed crossing on a 100-foot interval, providing hydrographic cross-sections and profiles of the Missouri River to be used in completing TS&L sheets for the SD DOT, providing hydrographic and overbank cross-sections on 8,000 LF of upstream bank on the Missouri River at a cross-section interval of 200 feet for the design of bank protection, and providing the hydrographic survey of six Missouri River valley sections to be used for hydrology investigations and geomorphology study. All survey work was performed, and final results provided in metric format.

Additionally, E/A also provided hydrographic cross-section and profiles of the Vermillion River to be used in completing the TS&L sheets for the SD DOT. The SD DOT requested additional re-survey of three valley sections of hydrographic data since the Missouri River was experiencing record flows over the course of the project. E/A was asked to perform this work during peak flows that presented extremely challenging conditions to the survey crew. E/A successfully contributed to the large undertaking of constructing a major new Missouri River bridge. to recycle flush water through the confinement barns. The screening and water treatment process reduces both odor and the acreage required for land application.
