Introduction 1.1.2 Pre-Feasibility Study Prior to undertaking this Environmental Impact Statement 1.1 Background to the Airport Link Project (EIS), the Brisbane City Council commissioned the TransApex pre-feasibility study into the most desirable means of 1.1.1 Strategic Planning delivering the Airport Link Project. The pre-feasibility study, The Queensland Government and Brisbane City Council has completed in March 2005, found that the Airport Link Project long recognised the need for a balanced and integrated was both financially and technically viable and would: response to the traffic and transport issues arising from sustained population growth and economic activity in the x support integrated land use and sustainable transport South East Queensland region. outcomes; x improve access to Brisbane’s middle and inner-ring The South East Queensland Regional Plan and the South East northern suburbs; Queensland Infrastructure Plan and Program 2005 – 2026 x reduce traffic congestion on certain arterial roads in the have been promulgated by the Queensland Government northern suburbs; to provide a framework for sustainable development in the x provide for efficient cross-city traffic, leading to region in response to the forecast population growth over environmental and economic benefits for the the twenty years to 2026. community; The South East Queensland Infrastructure Plan and Program x improve journey times for trips in the northern suburbs; (SEQIPP) provides in-principle support for the Airport Link x facilitate improved access to the airport, seaport and Project as part of an integrated approach to addressing the Australia TradeCoast; future transport needs of Greater Brisbane. SEQIPP identifies x lead to desired land use and economic outcomes by supporting inner-city urban renewal; and x support Council’s vision as outlined in Living in Brisbane 2010. 1.1.3 Detailed Feasibility Studies Following the pre-feasibility study, the Queensland Government and the Brisbane City Council resolved to proceed to detailed feasibility studies. These studies include: x an engineering feasibility study culminating in a preliminary concept design on which the EIS is based; and x an environmental impact statement (EIS), including a traffic and transport analysis. The Airport Link Project has been investigated and the concept developed in parallel with and during the course of this EIS process. The EIS investigations included a comprehensive a need to address public transport infrastructure, freight process of community and stakeholder engagement and transport links to the Australia TradeCoast, supporting active consultation. The EIS and consultation processes were transport choices, and improving road infrastructure. Airport integrated with the design development process to address Link is a key element of the road infrastructure identified community and technical issues as they arose, with the in SEQIPP as being necessary to cater for increasing travel intended outcome being a robust and sustainable project. demand based on sustained regional population growth. Should the Airport Link Project proceed, subsequent phases The Airport Link Project is also a key element of the Transport in project development will include a tendering phase and Plan for Brisbane and the Trans Apex initiative. It is intended to a construction phase, ahead of operation. The intended address deficiencies in the orbital road network of Brisbane operational life of the Airport Link Project is in the order of and to provide relief to congested roads in Brisbane’s 100 years. northern suburbs, connect activity centres, and provide a sound basis for future traffic management. These objectives can be achieved by linking to strategic road connections allowing cross-city travel movements to bypass the Central Business District and inner suburbs. PAGE - 1 1.2 Who are the Proponents? The Queensland Government and the Brisbane City Council are the Proponents for this detailed feasibility RBH phase of the Airport Link Project. The agencies of the Queensland Government with a key interest in the detailed feasibility study process are the Department of Main Roads, Queensland Transport and Queensland Treasury. The WINDSOR detailed feasibility study is being managed out of Brisbane City Council’s Major Infrastructure Projects Office on behalff of the Proponents. All parties have long and established records in the delivery of major infrastructure projects. BOWEN HILLS On completion of the Coordinator-General’s EIS Evaluation ICB Report process, the Proponents will determine whetherr or not to proceed to the next phase of the Project (ie thee tendering phase).
