LANE COVE TUNNEL
client Parsons Brinckerhoff/Thiess John Holland/RTA
Integrated urban and landscape design and documentation for a major infrastructure project in Sydney. The 3.6 km long twin tunnel connects the Gore Hill Freeway with the M2 Motorway in the northwest of Sydney. Key elements include; tunnel portals, retaining walls, bridges, sound walls in a unified design with earthworks, sensitive drainage concepts, cycle and pedestrian networks, plantings to reflect ecological themes and improvements to viaduct spaces. The architectural language is based upon triangularity, form and colour reinforces the identity of the project and provides a unique character to each element.
The portals form a series of sculptural elements in the landscape that assist in road legibility while also providing effective transitions between daylight and tunnel. The portal architecture is conceived to improve road legibility while providing a ‘transition’ between daylight and the tunnel interior.
The use of copper, fibrecement panels and composite panels provides each portal with its own character and reflects the setting surrounding each portal.
