In 1756 William Edwards finished Pontypridd Bridge, one of the most significant historical bridges in Wales. At a span of 44m, Pontypridd Bridge remained the longest single span UK bridge for several decades. This paper describes the building and testing of a 1/55th linear scale stone model of Pontypridd Bridge tested at the equivalent 55 gravities in a geotechnical centrifuge scale. The paper contains details of the construction of the model, including the cylindrical voids so necessary to the stability of the structure, the model instrumentation and the testing of the model to destruction. Conclusions are drawn on the behaviour of 3-D masonry arch bridges. For the covering abstract see ITRD E106406.
