Inner Sydney Transport Study

Improving travel times and supporting patronage growth in inner Sydney

scroll

The Project

INSW engaged LEK to develop a strategy for Inner Sydney transport, with a particular focus on improving travel times and supporting patronage growth on current bus corridors into the CBD. The strategy advocated an underground CBD bus solution for the major bus corridors from the north and west (Harbour Bridge, Broadway and Anzac Bridge), which would free up surface street capacity for pedestrians and potentially light rail on George Street from Central/Anzac Parade. A reference option was to make use of the old Wynyard tram tunnels and terminal, plus a bus terminal under a new Town Hall plaza (with potential connection to the Cross City tunnel as well as the Wynyard terminal).

The Task

MRCagney was engaged to support LEK’s strategic options assessment and to provide an operational perspective to infrastructure requirements for a CBD bus tunnel. MRCagney tested conceptual solutions for practicality, fitness for purpose and value-for-money and provided advice accordingly.  

This involved:

  • High level principles for efficient bus operations through a new tunnel, having regard to level of demand, and with a focus on “through-running”.
  • For the assumed operating solution, identifying the broad infrastructure needs for an underground solution.
  • Possible cost-effective design options to give surface bus routes appropriate access to underground sections
  • ​A number of options for tunnel, portal and station arrangements were considered from a strategic level concept perspective and further work was identified that would need to be carried out to pursue these.
