This article concerns the proposed construction of a concrete cable bridge over the Columbia River linking the towns of Pasco and Kennewick in Washington State, U.S.A. The bridge, with a main span of 300 metres, will be the second longest concrete bridge in the world and will be of unusual slenderness. The article describes the deck structure of the main spans, most of which is to be precast in large prestressed elements, each the full size of the bridge in cross section. The use of two erection gantries to build the bridge out progressively in balance, from each of the main piers in turn is next explained. The towers will be of concrete, and "starter" lengths of deck structure will be cast into place. Each erection gantries will cantilever beyond the finished deck but will not be balanced, the cantilever end being supported by erection cables. The method of placing the precast element is outlined. The article concludes by stating that the use of cable-stayed bridges, which are common in Europe, has only just been introduced in the U.S. /TRRL/
