Reinforced Concrete Bridge over River Alde.

The accompanying photograph is of a reinforced-concrete bridge, carrying the roadway over the River Alde, and is part of a scheme prepared by the County Surveyor, Mr. W. Jervis. The superstructure above the normal water level is in Portland Cement, and the whole structure is carried on twenty Ciment Fondu piles. A rather interesting feature of this bridge is the construction of the 4/13 ft. counterfooted walls; these are properly bonded into, and are part of, the bridge; in fact, the piers seen at the corners are really part and parcel of these walls. The walls at their outer ends are free, and can slide on the pile heads, a bituminous pad being placed between the pile cap and the underside of the wall base to allow for free movement. The wall is prevented from sliding outward from the roadway by being keyed into the inner pile cap.
