WestConnex: Tunnel design
Tunnel design challenges
• Traffic management systems and incident response
• Whole of life asset design
• Road capacity and design
• Tunnel cross section
• Ventilation and air quality
• Tunnel length
Tunnel design improvements – ventilation and air quality
• Tunnel Air Quality Advisory Committee
• Effective ventilation and efficient energy usage
• Location of ventilation outlets
• Managed portal emissions
Long tunnel considerations
• Long tunnels – M1 Pacific Motorway to M2 >8km with no intermediate
interchanges – WestConnex – tunnel travel of up to 13km with interchanges
• Driver experience – Safety – Lighting – Way finding – Geographical referencing – knowing where you are – Tunnel identity
