Abstract This paper reviews and describes experiences and the state-of-art of cable-supported rail-cum-road bridges with box girder. The application range of wide single box girder, vented box girders with two and three separated boxes is analyzed from the point of view of structural behavior, fabrication, transportation, installation depending upon the number of tracks, road lanes and different transversal locations of the pylon legs. Future trends of these bridges for multiple railway tracks and road lanes are discussed. A cable-stayed bridge with a main span of 520 m and three-separated-box-girder with different arrangements of the cable planes has been analyzed in a little more detail. The results reveal that the three-separated-box-girder is an effective solution for long span cable-supported bridges with multiple railway tracks and road lanes.
