The project is a part of the NSW Government’s 40-year vision for transport outcomes and aims to remove more than 2000 trucks from surface roads each day.
It will include twin four kilometres tunnels linking the M5 Motorway at Arncliffe to President Avenue, ramps between the main motorway tunnels and surface intersection, tunnel stubs for future connection to extend the F6 Extension, motorway support infrastructure including tunnel ventilation systems and new service utilities including a permanent power line.
Stage One of the project aims to allow motorists to bypass 23 sets of traffic lights on the Princes Highway, minimise disruption to the community and ease congestion.
The EIS identifies methods to avoid, mitigate, manage and offset potential impacts during construction and include environmental planning and management techniques along with urban design and landscaping treatments.
Preparation of a Construction Traffic and a Noise and Vibration management plans were identified as ways to reduce the impacts of construction on the surrounding area.
An in-tunnel ventilation system will be designed to maintain air quality and to monitor ambient and in-tunnel air quality.
The southern ventilation facility will be constructed in the industrial zone on West Botany Street to minimise impacts to residential communities, schools and the surrounding spaces.
A review of operations network performance will be undertaken at 12 months and five years from the project’s commencement to confirm operational traffic impacts.
NSW MPs Mark Speakman, Eleni Petinos, Lee Evans, Melanie Gibbons and Mark Coure said the project will deliver the missing link from Sydney’s south to the wider motorway network, making journeys easier, faster and safer.
“It will contribute to a more accessible, more liveable and more productive Greater Sydney and southern district, creating 5,300 jobs throughout the life of the project,” they said.
