The Author has said that the live load variation for a continuous bridge with equal spans was the same as that for simply supported spans and therefore there was no obvious advantage to be gained by the continuity. The writer has always thought that the solution lay in the use of alternate long and short spans. A full analysis of this problem has been made by Guyon1. There are also other methods of achieving continuity economically in prestressed concrete bridges by altering the geometry of the bridge at the supports.
