To help relieve congestion between Brisbane and the airport, the Queensland Government, Brisbane City Council, and a Thiess/John Holland Group/Macquarie Bank consortium (BrisConnections) built the Airport Link project.
It includes the longest tunnel in Australia (over 8 km (5.0 mi); 6 lanes) from the interchange between the Inner City Bypass and Clem Jones Tunnel (the 2nd longest tunnel in Australia) to the Airport Flyover over an improved Gateway Overpass which leads on to Airport Drive, cutting 16 sets of traffic lights.
It was completed in mid-2012.

The Northern Access Road project, completed in December 2009, significantly reduces traffic congestion on Airport Drive.
Moreton Drive, the 5 km (3.1 mi), multi-lane road network, linking Gateway Motorway with the airport terminals, provides airport users with a second major access route to terminals and on-airport businesses.
