Inspection and Repair of the M56 Thorley Lane Post-Tensioned Bridge

Post-tensioned concrete bridges have been in use since the late 1950s. This type of design was thought to bring with it the benefits of structures larger and more slender than had been possible by conventional design up to this time. It was not until the mid 1960s that the first signs of problems in this type of structure first showed up. T.J. Lee
