33 4.3 Evolving Design Approaches Several state highway agencies have been moving away from formal 3R design policies, not because they reject the concept of 3R design criteria, but rather because they believe that the 3R design concept has broader application than just to projects performed as part of the Federal 3R program. Such states formerly had 3R design policies, but have replaced those policies with new, more broadly based approaches.
