The AirportlinkM7 is a 6.7km twin tunnel in the northern suburbs of Brisbane connecting the Clem7 and Legacy Way tunnels (via Inner City Bypass) to the Brisbane Airport and Australia TradeCoast precinct.
World-class safety features include variable speed and message signs, advanced fire safety systems and cameras automatically detecting variations in traffic flow.
When you travel on AirportlinkM7 you will avoid up to 14 sets of traffic lights and reduce travel time by up to 88%.
The AirportlinkM7 tunnel clearance height is 4.6 metres.
If you drive a vehicle over this height you won't be able to use the tunnels. Detection systems outside the tunnel notify drivers of height limits. Warning signals are initialised if the height limit is breached. All vehicles exceeding the height limit will be advised to take an alternate route.
If drivers of overheight vehicles proceed, entry will be prevented by an overheight barrier structure.
We also monitor the internal and external air quality of the tunnel. Air quality monitors in and outside the tunnel constantly measure the presence of carbon monoxide (CO), nitrogen dioxide (NO2), fine particles and visibility levels.
