BrisConnections is dedicated to ensuring that AirportlinkM7 is operated in accordance with environmentally conscious and sustainable practices.  Our approach to environmental management and protection practices is designed to minimise the impact of AirportlinkM7 on the environment. 

Noise
Baseline monitoring was undertaken for operational traffic noise in early 2008, six months prior to the start of construction.  Within twelve months of operation commencing, a comparative study will be undertaken to confirm that traffic noise remains compliant with noise goals from the Department of Transport and Main Roads.

The ventilation station outlets have been designed to achieve acoustic goals when in full operation so as to not adversely affect community members in nearby properties.

Air quality
AirportlinkM7 is designed to provide a safe driving environment for motorists.  As the tunnel will carry thousands of vehicles per day, maintaining the quality of air both in and outside the tunnel is an important part of day-to-day operation.

BrisConnections operates AirportlinkM7 in accordance with conditions established by the Queensland Co-ordinator General.  These conditions are based on standards recommended by the World Health Organisation for the maximum allowable level of vehicle emissions in the air both in and outside the tunnel.
