 The Bridge was designed and built by the Ferro-Concrete Company of Australasia, Ltd., under the supervision of the City Engineer, the contract price being £31,918. The total completed price was £35,441, while a further £5,000 was spent in acquisition of land and in legal and other expenses.

The main arch consists of two ribs, 6 feet by 4 feet 7 inches at the abutments, 10 feet by 4 feet 3½ inches at the quarters, and 5 feet 6 inches by 4 feet at the centre hinge. The abutment hinges are of cast steel, and are carried on steel girder grids. The total length between the abutment hinges is 315 feet, the rise from the bottom hinge to the central hinge is 84 feet, and the greatest height above the creek 147 feet. Six of the straight girders are of the open type and the remainder solid. There are three girders to the width of the bridge, the two outer being under the kerb line. The footpaths are carried out from the outer girder on cantilevers. The width of the bridge between parapets is 36 feet, of which 21 feet is carriage way, and the remainder, two footpaths of 6 feet each.

It is interesting to note that the total amount of steel used was over 337 tons, and of concrete 5,504 cubic yards.
