EVENT DETAIL

Abstract:

A one-mile-long bridge over the Missouri River (SD44 Platte-Winner) in South Dakota is scheduled for replacement this decade. Agreement on a new location required a multi-agency, multi-disciplined approach that has challenged SDDOT practices, in areas where federal practices are changing - Section 4f, Section 106, and Section 408. A project update will be shared with ongoing lessons learned, along with a look into the expected design challenges.
