As part of Brisbane’s new road link connecting Brisbane to the airport, TCL provided specialist urban design for all major gateway experiences.

The consultation included recommendations on tunnel portals, ventilation stacks, noise walls and the aesthetic design of engineering structures such as bridges, sections of elevated road, retaining walls and tunnel lighting.

A major feature of the driving experience is two large gateway elements at each end of the main tunnel. One is a large curtain wall at the city interface, an urban gesture that responds to the urban scale of the freeway interchange. The other, a lush sub-tropical green vertical garden, the largest of its kind in Australia, descends adjacent to the portal at the airport side of the tunnel.
