NorthConnex is a nine kilometre tunnel that will link the M1 Pacific Motorway at Wahroonga to the Hills M2 Motorway at West Pennant Hills, removing around 5,000 trucks off Pennant Hills Road each day. NorthConnex will be the longest road tunnel project in Australia.

Integration in to existing motorways has been key in the project. Dallas Delta has been able to adapt some of our designs and work with the project team to provide a seamless integration of these technologies.

Work is expected to be completed in 2019.
