The alignment of East Terrace near Rymill Park will change today as the $160 Million O-Bahn City Access Project marks another milestone.


“Not only does the O-Bahn City Access Project represent a significant investment in building a stronger public transport network, it will provide enormous benefits to the more than 79,000 road users who navigate this part of the Inner Ring Route and are creating valuable work for local businesses.” Acting Minister for Transport and Infrastructure Martin Hamilton-Smith said.

This afternoon traffic travelling on East Terrace between Grenfell and Hutt streets will be switched to a new road, to the west of the existing alignment, in preparation for the next stage of the O-Bahn project.

“The realignment of East Terrace will improve traffic flows through the city as construction continues on the O-Bahn City Access Project, while also adding valuable area to Rymill Park.”

The next stage includes new excavation as part of the $6 Million major tunnelling earthworks component, which has been unbundled to maximise the benefit to local South Australian businesses.

The work has been released by the major contractor McConnell Dowell Australia under the South Australian Industry Participation Policy, giving local businesses a bigger share of major Government projects.

“Knowing that we will be supplying our services to a Government project of this magnitude and duration provides our business with additional stability.” CB &S Civil Operations Manager Craig Hill said.

By splitting up the earthworks package, and awarding components to small-to-medium contractors rather than a single contractor, an additional eight South Australian businesses are now working on this stage.

“Major construction projects valued over $50 Million in the 12 months to the end of April 2016 had an estimated work package of dollars spent in South Australia of $637 Million out of $698 Million.” Mr. Hamilton-Smith said.

Across the project, local South Australian businesses and contractors have already benefitted from $64 Million of works on the project.


The $160 Million O-Bahn City Access Project will create a 650-metre tunnel linking priority bus lanes on Hackney Road and Grenfell Street to improve travel times and reliability for Adelaide’s busiest public transport network, as well as for traffic on the Inner City Ring Route.

The new alignment will move East Terrace further west between Grenfell and Pirie streets, incorporating 710 sqm of road reserve to Park Lands.

The fountain in the western corner of Rymill Park was removed before construction of the new alignment and will be reinstated next year during remediation works, which will include tree plantings.

The 8 SME’s (Small to Medium Enterprises) that are benefitting from the unbundling of the earthworks package are:

  • Marzilli Transport
  • Page Excavations
  • CB&S Civil
  • CJP Hire
  • ACT Hire
  • Envirosweep
  • Lucas TCS
  • MK2 Recruitment

Contractor McConnell Dowell is committed to ensuring South Australian SME’s have a chance to share in the benefits of the O-Bahn City Access Project.

Approximately 450 jobs are expected to be created during construction with completion scheduled for late 2017.

The South Australian Industry Participation Policy is managed by the Industry Participation Advocate, who ensures local businesses get first go at the almost $4 Billion worth of goods and services contracts let annually by the State Government.

Data from the State Procurement Board shows that 90% of the value of goods and services contracts was let to South Australian suppliers in 2014-15. This compares to 79% in 2013-14 and is a massive turnaround from just 51% in 2012-13.
