Why is the Western Ring Route needed?

• The WRR
• Provides a strategic alternative to SH1 and the
  Auckland Harbour Bridge
• Delivers more predictable travel times and links
  major residential and commercial areas,
  particularly between west and south
• Boosts Aucklands economy
• Complements investment in rail and public
  transport
• Connects Manukau, Waitakere, Auckland and North
  Shore cities

Option selection

• Consultation since 2000
• Numerous alignments considered
• Waterview interchange endorsed by councils in
  2005 and confirmed by Transit in 2006
• Community resisted level of disruption associated
  with cut and cover option and asked for further
  undergrounding
• Investigation of undergrounding
• Tunnel announced as preferred option in February
  2008

Why a tunnel?

• Minimises
• Overall social and environmental disruption
• Construction effects which are confined to
  portals and interchanges -these effects would
  apply to all other options
• Impacts on parks, reserves and Oakley Creek
• Shorter route
• Maximises community calls for more undergrounding
