Building the NorthConnex

Building NorthConnex: Australia’s Largest Tunnelled Motorway

Built by a joint venture between Lendlease Engineering and Bouygues Construction Australia (LLBJV), early work started in February 2015 and the first tunneling work started in April 2016.
The scale of the NorthConnex project, and the densely-populated region in which it is situated, presented a number of unique challenges throughout design, surveying and construction.
