USACE Lock and Dam 3 Navigation Improvements and Lower Embankment
Kraemer completed two successive award-winning design-build projects for the USACE St. Paul District with strict environmental regulations: the Lower Bank Improvements and Lock and Dam 3 Navigation Improvements projects. Work included extending a guidewall 875 feet upstream and modifying the river flow to reduce the outdraft condition at the lock and dam. Unique challenges included protecting Bald Eagles, several tree species, and mussel beds. No road access to the project area required all construction to be accessed by water using barges.
