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

Excerpt from Wikipedia

The Morell Bridge is an arch bridge over the Yarra River in South Yarra, Melbourne, Victoria, Australia. Completed in 1899 by John Monash and J. T. N. Anderson, it is notable as the first bridge in Victoria that was built using reinforced concrete.

It features decorations on the three arch spans, including large dragon motifs and ornamental Victorian lights. The gutters on the bridge are cobbled bluestone, with a single lane bitumen strip running down the middle. The Bridge is listed on the Victorian Heritage Register.

Originally known as the Anderson Street bridge, it was named the Morell Bridge in 1936 after Sir Stephen Morell who was a prominent Victorian businessman and Lord Mayor of Melbourne between 1926 and 1928.

On June 7, 1998 the bridge was closed to motor vehicles as part of the CityLink project. It is currently used by cyclist and pedestrian traffic, connecting the Royal Botanic Gardens to the Olympic Park precinct.
