WestConnex 3A

Design-build of two motorway tunnels

Underground Works

Australia, 2018-2023

General description

After being awarded the contract to construct and design the NorthConnex motorway link, Bouygues Construction Australia has once again been chosen to build two 7.5-kilometre motorway tunnels as part of the WestConnex project in Sydney. These 4-lane tunnels will link the M4 motorway at Haberfield to the new M5 motorway at the St Peters interchange. Once completed, the 33 kilometre-long WestConnex motorway will make life easier for the 5.25 million people living in Sydney, Australia's most populous city. By providing better links between the city centre and suburban districts, the new motorway will also support the region’s economic and demographic development.
