Commenced: September 2024
Description
Ventia and its Alliance partners, John Holland Group, Bouygues, Arcadis, and Jacobs have been selected to deliver the River Torrens to Darlington (T2D) Project, the final 10.5km section of Adelaide’s 78km North-South Corridor.
The T2D Project will be a ‘managed motorway’ incorporating a range of intelligent transport systems (ITS) in the motorway and tunnels, to manage traffic flows, improve safety, and provide travel time reliability. These systems include:
- Dedicated 24/7 traffic management centre (TMC)
- Coordinated ramp signalling
- Speed and lane use management
- Automated incident detection
- Dynamic variable messaging signs (VMS) to provide real-time information to motorists like incident warnings and likely travel time
- Tunnel closure system
- Automatic incident detection
- CCTV cameras for constant road monitoring and quick incident management
- Lane use management system to control speed limits and lane closures for optimised traffic flow and safety
- Fire detection and suppression systems to activate sprinklers
- Radio rebroadcasting, so traffic management centre personnel can broadcast safety messages to motorists in the tunnels via their vehicle’s radio.
Upon completion of construction, the Maintenance and Incident Response (M&IR) services will commence under a new contract. The scope of these future services includes the open motorway, tunnels, managed motorway systems and intelligent transport systems (ITS) of the 10.5km T2D section, and 24/7 Roadside Assistance and Incident Response Services for a 26km section of the North-South Corridor, inclusive of the T2D.
The Project Alliance Agreement contract was awarded in September 2024 with an expected completion of 2031. The subsequent M&IR contract is expected to be finalised prior to construction completion and will be an initial term of 10 years, with two three-year options to extend.
