Notes
Built in a dry channel during diversion of the River Yarra. North abutment on timber piles driven to rock, surmounted by horizontal timber grid supporting concrete abutment. South abutment built directly on rock. Two river piers built on rock (concrete with upright rails as reinforcement). Monier arches built on falsework supported from dry bed of channel. Reinforcing grid top and bottom. Moist 'compo' consisting of 3 parts sand to 1 part cement rammed into place by hand. Spandrel retaining walls (probably mass concrete) built along edges of arches. Void filled with rammed earth to support pavement.
Design loading: 15.2 tonne steam roller plus 4.8 kPa distributed
