The ability to divide the main arch span into separate ribs - once only possible with steel - was now a standard feature of these new concrete creations. Detailed chapters explain the construction and design of bridge abutments and piers, and the footings that connect them to the bridge.
Just like full size railroads soft soil tends to wash away or onto track during wet weather. It was replaced by a fill causeway in the s, and is now being salvaged for its timber. This ability to transfer the weight of the main span to the shore arms was also a major advantage during construction since there was no need for false work over the deepest parts of the river.
