The largest pontoon bridge in the world and the first to be built of reinforced concrete presented numerous problems of design and construction, those resulting from the use of concrete being of course original. Some of these are oresented. Why a pontoon bridge was selected; why it was built of reinforced concrete: the essential features of the design; how the concrete was made watertight; what results were achieved in this respect; how the contractors built the 25 pontoon sections; how they were assembled, interconnected, anchored; what pro- vision is made for the passage of large ships: what are the bridge’s notable features in service -all of these questions and topics are the material with which this paper deals.
