WestCONnex is based on an already weak business case and the analysis of road demand is poorly articulated. However WestCONnex will not review its analysis of the business case since it would be neutral or rejected.
Implications for Rozelle and Lilyfield
- According to a recent presentation by Stuart Ayres (Minister for WCX), the proposed Rozelle interchange would be the largest interchange in the southern hemisphere.
- St Peters interchange would be the second largest interchange in the southern hemisphere.
- There would be around 100 lane-kilometres of tunnels under Lilyfield, Rozelle, Balmain and Birchgrove – in Ayres’ estimation twice the extent of tunnelling for the Snowy Mountains Hydro Scheme.
- The lowest point of the tunnels would be 70 – 100 metres deep.
- The highest point of the tunnels would be just 4 metres deep.
Due to the depth of the tunnels there would be many serious safety issues including:
- evacuation in an emergency
- access for emergency services
- the ability of the exhaust systems to push the emissions 100 metres upwards
- noise, dust, vibration during construction
City of Sydney Alternative
Since the State Government’s own plan does not meet WestCONnex’s original objectives (e.g. facilitating freight movement to and from Port Botany), the City of Sydney has proposed an alternative solution, which does meet these objectives and mitigates the negative impacts. This is of great importance since the city’s Central Business District contributes 24% of the NSW economy and 12% of the state’s employment. The City cannot afford to have a transport solution which will NOT solve the congestion. It is essential that freight, trades, services and construction vehicles do not waste time sitting in traffic.
The City of Sydney’s alternative plan seeks to:
- Minimise the need for major infrastructure
- Consider all options to maximise the use of the existing infrastructure
- Develop infrastructure which considers other infrastructure and land use changes that have occurred.
These aspects are important because since WestCONnex was approved there have been new and competing transport infrastructure and land use changes that will significantly alter the original modelling undertaken by WestCONnex.
