This article describes reconstruction work carried out on the Springfield bridge in natal province. The history of the bridge which was first built in 1890 is briefly outlined. By the 1970's the six span composite steel and concrete bridge was due to be replaced by a wider structure. The design chosen by the natal roads department utilized the original two large piers and two original abutments. Partially post tensioned prestressed voided beams with flanges were cast on each side of the existing structure to widen the bridge by four metres each side. This was the first use of partially prestressed beams in natal. A 150 mm topping was cast on the original deck tied together using longitudinal hinge joints, and work was completed in 1983. (TRRL)
