Book excerpt: Excerpt from Continuous Concrete Bridges Only single bearings are required at interior supports of continuous bridges, materially reducing the width of piers compared to simple spans. Cost of the substructure is thereby reduced; obstruction to stream flow is minimized and the tendency to scour resulting from large piers is lessened. Continuous bridges require fewer expansion joints, which reduces first cost slightly and the expense of maintaining joints. In a well designed continuous girder bridge, the depth of sections follows closely the moment requirements, varying from a minimum at the center of spans to a maximum at the supports. The effect of dead load on the design is reduced accordingly. The variation of section from center of spans to sup ports is also favorable to the stress requirements.
