The design and construction of the 800 M prestressed concrete, box girder Byker viaduct section of the Tyne and Wear Metro system is described. Design studies showed that for the western valley section of the viaduct piling through coal measures would be required, grouting under pier foundations to consolidate coal seams would be necessary, the valley flanks were unsuitable for founding falsework, and, the overall design should be in sympathy with existing bridge structures. The eastern Byker hill section of the viaduct required foundations in shallow pads located in boulder clay. Details are given of passenger train loadings of the structure which governed fatigue design and critical braking forces while the slow-moving works trains governed the direct bending and shear loads.
