The design concept is carefully engineered to incorporate new high performance structural materials. As a result, a number of special features evolved to produce an efficient bridge design. Along with structural system development, a design methodology is presented which consists of two stages. First, an optimal preliminary design based on a simplified model is obtained. The combination of a simplified model based on the Ritz solution of a transformed plate with a formal optimization scheme produced an effective tool for preliminary design.
