Mission Statement

We are committed to produce quality plans for the construction of highway structures. Through our bridge management system we strive to assure that bridges are not only safe, but are hydraulically, functionally and structurally sound. We do this in a spirit of teamwork with all Nebraska Department of Roads Divisions, Districts and other organizations, for the benefit of the people.
