WestConnex Delivery Authority  – Air Quality Impact Assessment

WestConnex is the largest transport project in Australia, linking Sydney’s west and south-west with the CBD, Sydney Airport and Port Botany. The 33 kilometre WestConnex motorway will run from Parramatta along the M4/Parramatta Road corridor to Rozelle, before heading south through Camperdown to St Peters and Sydney Airport, and then west to Beverly Hills.

The Challenge

It will be delivered in three stages, with the final stage to open to traffic in 2023. Work on the M4 Widening, which is part of Stage 1, gets underway in 2015. Further planning work to develop the New M5 and M4-M5 Link is continuing.

Optimising outcomes and measuring performance sums up our role as strategic advisor to the Westconnex Delivery Authority for air quality aspects of the project. Over the last twelve months we have been integral to the production of the air quality impact assessments for the M4 East (Strathfield to Haberfield) and New M5 (Beverly Hills to St Peters) road tunnels.

The Solution

The past year has also seen the expansion of the ambient air quality monitoring network for the project from six to twelve monitoring locations, strategically placed to monitor performance along the route. These monitoring stations represent high accuracy, laboratory grade instrumentation to provide accurate information on air quality performance now and into the future.
