WestConnex

WestConnex motorway was originally developed as three separate connected projects, the M4-M5 Link, the M4 widening, and the M5 widening and tunnel duplication. The project had a tight timeframe, a large range of interfaces and was a key priority of both the Federal and State Governments. 

The key objective of the project was to relieve road congestion to improve the speed, reliability and safety of travel on the M4, M5 and Central Business District (CBD)/airport/port corridors, including parallel arterial roads.

Roads and Maritime Services (RMS) appointed North as a specialist Infrastructure Estimator to develop the cost estimates for WestConnex motorway through the options and Concept Design development stage.
