Tech talk – balanced cantilever method of bridge construction

One of the greatest challenges presented by the balanced cantilever bridge construction method is the design of the “hinge detail” at expansion joint locations, where the tips of the cantilevers from each side meet at mid-span. This hinge detail must be able to withstand not only the continuous movements of the adjacent spans but also the continuous fatigue loading from every vehicle that crosses the bridge – transferring its weight from one cantilever to the other, with resulting reversal of vertical loading. A modern high-tech solution to this challenge has recently been implemented in the construction of a new multi-span bridge over the River Brahmaputra near Tezpur in eastern India.
