align="left">Elimination of expansion joints in bridge decks results in initial economy and long-term durability. It provides a smooth-riding surface, minimizes maintenance cost caused by water leakage, and provides a relatively high span-to-depth ratio of the superstructure. This paper presents a summary of the results of a project whose dual objectives were to reduce the cost of bearing devices used in? jointless bridges and to optimize the girder/pier joint details for economy, constructability and aesthetics. Criteria for selection of bearing devices as a function of load levels, translational and rotational? capacities, simplified diaphragm details, simplified fixed and expansion bearing details, and enhancements of bridge aesthetics are presented. Cases where a sharp skew exists in the bridge are covered. With the large bottom flange of modern I-girder shapes, it is shown how girder ends are produced with a skew to minimize the pier width.
