- A City North Infrastructure Pty Ltd (CNI) was a wholly State Government-owned company established to manage the procurement, delivery and contract management phase of the Airport Link, Northern Busway (Windsor to Kedron) and Airport Roundabout Upgrade projects on behalf of the State Government.
- Q Why was CNI established?
- A
Combined, the Airport Link, Northern Busway (Windsor to Kedron) and Airport Roundabout Upgrade represent the largest and most complex road infrastructure project currently being undertaken in Australia.
Given the significance of this vital project, a range of delivery options were considered as well as various project governance models. The CNI model was chosen as the company can be responsible for all of the activities, costs, risks and liabilities associated with the project with one transparent and accountable entity.
- Q How is the project monitored?
- A The Coordinator-General has placed a number of conditions around the project (to view the conditions click here)
- Q What is the role of the Coordinator-General?
- A
The role of the Coordinator-General was established under the State Development and Public Works Organisation Act 1971 (SDPWOA). The Act provides the Coordinator-General with wide ranging powers to promote economic and social development and job opportunities through coordinating and implementing large scale projects and developments (see the website of the Coordinator-General for more information).
On the Airport Link project, the office of the Coordinator-General monitors the project’s compliance with the Coordinator-General’s conditions. The conditions are outlined in the following reports:
- Q Who oversees works done on the Northern Busway (Windsor to Kedron)?
- A
The Northern Busway (Windsor to Kedron) as with all other Busways in Brisbane, was established under the Concept Design and Impact Management Plan (CDIMP). This plan is a highly detailed document used to assess a range of environmental, social and economic issues related to busway and transit infrastructure. In addition to the CDIMP, the contract between the State and the company constructing the Busway, requires that Thiess John Holland comply with the planning conditions set for Airport Link (for example levels on dust, noise and traffic management are all the same).
As with all other infrastructure projects, regulatory agencies including Department of Environment and Resource Management (DERM), Department of Transport and Main Roads, Workplace Health and Safety and Brisbane City Council have their usual jurisdiction over construction activities on the Northern Busway (Windsor to Kedron).
- Q What is the role of CNI?
- A
CNI is the State’s representative on the Airport Link, Northern Busway (Windsor to Kedron) and Airport Roundabout Upgrade projects. CNI represented the State’s interests in the projects and liaises closely with the project team on the full range of aspects of project delivery.
As part of its role, CNI monitored the project’s compliance with the Coordinator-General’s conditions and tests BrisConnections/ Thiess John Holland's activities and proposed activities against the conditions and the Project Deed. As part of this work, CNI reviewed all notifications and materials prior to their distribution to the community. CNI also monitored project works by conducting ad-hoc independent environmental monitoring, considers possible breaches of conditions, conducted inquiries into the project’s complaint management and regular site visits.
After CNI assuming project responsibility in December 2006, the company kept the community up to date with the progress of the projects via:
- Project Info Line (1800 990 038, freecall)
- CNI info email (mailto:info@cni.qld.gov.au)
- Community open days
- Ad-hoc newsletters
- CNI also attended the project’s Community Liaison Group (CLG) meetings during construction and meets regularly with individual residents and businesses.
- Q How is CNI accountable?
- A
An Annual Report was tabled in the Queensland Parliament by the Minister for Infrastructure and Planning and each month, a Shareholder Report was sent to all CNI shareholders.
In addition, External Auditors from the Queensland Audit Office conducted an annual Independent Audit Report, which was included in the yearly financial statement.
CNI also provided extensive contractual and project documents via the CNI website (www.citynorthinfrastructure.com.au) and provides detailed response to enquiries from the media, community and other stakeholders where it can do so without breaching commercial arrangements or privacy rules.
- Q Why was Airport Link built?
- A
By 2026, the population of South East Queensland is expected to increase from 2.6 million to about 3.7 million, with Brisbane bearing the brunt of that growth.
The existing road network cannot accommodate the expected increase in traffic associated with this growth as more and more people travel to the inner city to access employment, commercial and administrative services, and cultural and recreational opportunities.
Every year SEQ roads are becoming more congested during peak periods. Traffic pressures are causing delays and frustration for both motorists and public transport users, especially on major north side arterials such as Sandgate Road and Lutwyche Road.
Ongoing development of the Australia TradeCoast precinct will lead to employment and residential growth causing even more traffic. The precinct comprises 8000 hectares of commercial and industrial land surrounding Brisbane’s seaport and domestic and international airports.
- Q What are the key benefits of Airport Link?
- A Airport Link:
- enables motorists to bypass 18 sets of traffic lights between Bowen Hills and the airport
- adds six extra lanes to the traffic network between Bowen Hills and Kedron and four extra lanes between Kedron and Toombul
- gives motorists using the Clem7 new exit options at Kedron and Toombul
- is expected to reduce traffic on Lutwyche Road by up to 40%.
- Q What are the key benefits of the Northern Busway (Windsor to Kedron)?
- A
The Windsor to Kedron section of the Northern Busway includes:
- 1.5 kilometres of tunnel under Lutwyche Road and Gympie Road
- state of the art bus stations at Lutwyche and Kedron and new bus shelters;
- ability to cater for 47,000 public transport trips per day by 2016 – more than five times the current number
- a bus every 20 seconds by 2026
- part of a busway network that will eventually span the city, combining with the existing rail network to complete the city’s major public transport system.
- Q Are buses still be able to use the surface roads or do they only use the Northern Busway tunnel?
- A
Brisbane City Council’s local bus services still operate in northern Brisbane suburbs along the surface roads. However a fast, frequent public transport bus service connecting the city and northern suburbs operates on the Northern Busway.
More details on bus services and stops is provided by TransLink at Translink's website.
- Q Where is the busway underground?
- A The busway is underground for approximately 1.5km between Truro Street, Windsor and Sadlier Street, Kedron, surfacing at the two new, architecturally designed busway stations located at Lutwyche and Kedron.
- Q Can buses use the Airport Link tunnel?
- A Yes
- Q Why was the Windsor to Kedron section of the Northern Busway being delivered with Airport Link?
- A
Building the section of the busway between Constitution Road, Windsor and Sadlier Street, Kedron with Airport Link ensured efficiency and better value for the State. This stage had similar works (tunnelling) and significant capital works closely linked to Airport Link, particularly in Kedron.
The construction of the two projects offered a significant opportunity to drive better value for money and better outcomes for the local community (for example, by avoiding separate construction of two major projects). - Q When did construction begin on the Airport Link and the Northern Busway (Windsor to Kedron)?
- A
Construction of the Airport Link and the Northern Busway (Windsor to Kedron) projects began in November 2008. The start of construction was marked by an official sod-turning ceremony attended by Premier Anna Bligh on 6 November 2008. Both projects opened in mid-2012.
- Q What are the benefits of the Airport Roundabout Upgrade?
- A The Airport Roundabout Upgrade offers:
- reliable and fast access to and from the domestic and international airport terminals
- reduced traffic congestion and delays for business, Brisbane’s residents and visitors
- savings of more than 10 minutes for trips going to and from the airport during peak periods
- improved road safety
- reduced traffic delays and improved reliability with the overpass providing a direct connection between the East-West Arterial Road and Airport Drive.
- Q How long did construction take on the Airport Roundabout Updgrade?
- A The construction of the Airport Roundabout Upgrade began in April 2009, four months ahead of schedule and the Airport Flyover was fully operational by February 2011.
- Q What was the cost of the Airport Link, Northern Busway (Windsor to Kedron) and Airport Roundabout Upgrade?
