This article reports on progress with the construction of the Newbridge viaduct across the river Dee in North Wales; it will be part of the Newbridge bypass, which has a single carriageway 5 km long. The bridge crosses a deep gorge with one of the highest structures to be built using the balanced cantilever method. At its highest point, the deck of the five-span structure is 60 m above the valley floor. Construction of this high-level superstructure presents a formidable challenge, especially as the design used is more difficult to implement than the more expensive design that was previously proposed. There is a tight schedule to meet if the bridge is to be opened on time in May 1990. At the time of writing, two piers had been constructed, together with the first balanced cantilever. Substantial permanent works will also be carried out deep in the ground; eventually, they will be out of sight. The viaduct is designed to have a life of 120 years. (TRRL)
