Client: RMS Motorways

The concept of connecting the WestConnex Motorways to northern Sydney was developed through 2015 and 2016 through a Strategic Business Case. InfraSol were participants in the Beaches Link route selection and immersed tunnel concept design for crossing Middle Harbour.
Government approved RMS in 2017 to advance development of a Final Business Case and Project Definition and Delivery Report. The significant issues addressed in the constructability were the:
route and engineering form of the tunnels; and
reconfiguration of the Warringah Freeway to integrate the various connections in a staged approach.
