When complete the Rozelle Interchange will provide a new underground motorway network to connect some of Sydney’s busiest commuter corridors. It will reduce congestion in the inner west of Sydney and provide essential connections across Sydney. The project will also turn a disused railyard site into a vibrant green space with a new wetland, active transport links and recreation areas for all ages.
Consisting of 23kms of tunnel, four cut and cover tunnel portal structures, 12 bridges and two ventilation facilities connected to a fully undergrounded ventilation system, the Rozelle Interchange represents one of the most complex underground motorways ever undertaken.
It will completely transform a disused rail yard site to deliver up to 10 hectares of green parkland space and provide new active transport options to the community.
Our team was recently awarded the Southern Tunnelling package of the Western Harbour Tunnel, extending the package of work to build a new connection across Sydney Harbour.
