Search WHAT WE DO WHO WE ARE FEATURED PROJECTS CAREERS CONTACT US NEWS FEATURED PROJECT KLJ AMONG OTHERS FROM ACROSS NORTH AMERICA COME TOGETHER FOR BRIDGE PROJECT KLJ was the prime consultant for planning, environmental assessment, design and construction inspection of the Four Bears Bridge replacement. The replacement structure is in a picturesque setting spanning 4,500 feet over Lake Sakakawea on the Fort Berthold Indian Reservation in northwestern North Dakota. PROJECT Professionals for the project were hand-picked from across the United States and Canada to form a team ready to address the project’s various complex issues. Lake Sakakawea is a reservoir on the Missouri River formed by construction of Garrison Dam. The lake can reach depths up to 90 feet at this location, resulting in significant ice and wind loads on the structure. The depth, ice loading, and relatively soft bearing soil resulted in challenging foundation design. SOLUTION Steel and concrete bridge alternatives were designed and detailed for competitive bidding. Although the concrete alternative was constructed, KLJ was responsible for most of the steel alternative structural design, as well as providing management and coordination. Additional services provided by KLJ included: Preparation of an Environmental Assessment Obtaining environmental clearances and permits General civil engineering services Coordination between design team, state and federal agencies, utility companies, local communities, and the Mandan, Hidatsa and Arikara Nation Survey control and accuracy in deep water conditions prev next RESULTS Throughout the entire National Environmental Policy Act and Context Sensitive Design processes, there have been close to 200 individuals from the Three Affiliated Tribes involved in nurturing the project and guaranteeing that the finished bridge would utilize Native American culture to reflect a design that is truly context-sensitive.
