New shared use bridge opens on O-Bahn tunnel project

12 July 2017

A new shared use bridge for cyclists and pedestrians has been completed, improving access and safety as part of the $160 million O-Bahn City Access Project.

The bridge, which spans the River Torrens, is 3.4m wide and 78m long and constructed of three 55-tonne concrete beams, each 26 metres long and made by local business Bianco.

Each of the beams used steel billet for reinforcing from the Whyalla steelworks and approximately 320 cubic metres of concrete was used in the bridge.

The handrail is approximately 160m long and is made from stainless steel tubing material supplied by local business Specialised Solutions.

The bridge will connect to a new dedicated shared use path on the western side of Hackney Road between the River Torrens and Botanic Road, which is due for completion late in the third quarter of this year.

The River Torrens Linear Park path reopened late last month after major construction works on the shared use bridge, as well as widening works to the Hackney Bridge to create a new dedicated bus lane.

The Hackney Bridge widening works involved strengthening the underside of the bridge structure and placing 35 cubic metres of concrete and six tonnes of new reinforcement using high quality steel billet from the Whyalla steelworks.

The $160 million O-Bahn City Access Project will create a 670-metre tunnel linking priority bus lanes on Hackney Road and Grenfell Street.

In May the final roof planks for the tunnel were installed on Hackney Road.

The tunnel will improve travel times and reliability for Adelaide’s busiest public transport network, as well as for traffic on the Inner City Ring Route.

The O-Bahn City Access Project is on schedule for completion by the end of 2017.
