Concrete bridges have evolved significantly in the past 25 years. The introduction of pre-stressed concrete led to the construction of major bridges like the Clifton Bridge and the Medway Bridge. The use of precast segmental construction, along with other factory production advancements, influenced the design of shorter bridges. By the 1960s, most bridges were made of concrete due to the motorway construction boom. New construction techniques and materials have allowed for more innovative bridge designs, like the sliding technique at Frodsham and the extrusion process at Sonning. Future developments in concrete bridge design are also discussed.
