New bridge to improve access and safety in Adelaide

A new shared cyclist and pedestrian bridge, as part of the $160 million O-Bahn City Access Project, in Adelaide is now complete.The 3.4m wide and 78m long structure spans the River Torrens and is constructed out 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.

“While the O-Bahn project will significantly improve travel times and reliability for buses, cars and all vehicles on our Inner City Ring Route, it’s also an opportunity to improve safety and access for pedestrians and cyclists,” said South Australia Transport and Infrastructure Minister Stephen Mullighan in a statement.

“This new shared use bridge and path on the western side of Hackney Road will make it much easier and safer for cyclists to cross the River Torrens, in particular by separating cyclists from road traffic.”

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 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 steel billet from the Whyalla steelworks.

“The Torrens Linear Park is one of the most popular cycling and walking routes in Adelaide, stretching 30 kilometres from Athelstone in the east to West Beach in the west,” said Mr. Mullighan.

“In addition to creating shared paths with our major infrastructure projects, the South Australian Government is investing more than $20 million in cycling infrastructure including in the CBD and on greenways and bike boulevards.

“It’s estimated that for every kilometre cycled in Australia, $1.43 in economic benefits are generated and about half of that is savings on public health costs.”

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

It is on schedule for completion by the end of 2017.
