Development in Concrete Bridges

The range of standard pretensioned bridge beams was developed between 1955 and 1975. The bridge stock built using these beams has been remarkably durable, and the major durability problem with these, as with bridges of in situ concrete and steel beam construction, has been chloride attack from road salt channelled through deck joints onto often poorly detailed and maintained substructures.
