client WestConnex Delivery Authority

The 33 kilometre WestConnex is being delivered through a series of projects in three stages over 10 years.

Stage 1: M4 – Parramatta to Haberfield
Stage 2: New M5 – Beverly Hills to St Peters
Stage 3: M4–M5 Link– Haberfield to St Peters.

Apart from the existing surface sections of the M4 and M5, WestConnex will be constructed in tunnel. This minimizes the need for property acquisition and disruption to communities along the route. Stage 1 is being delivered in two parts, with the M4 widening due to be complete in 2017 and the M4 East in 2019. Stage 2 of WestConnex, the New M5 has been accelerated as a result of a loan agreement with the Australian Government, and subject to planning approval is also scheduled for completion in 2019. Stage 3 will join the first stages together and is currently scheduled for completion in 2023.

Yvonne von Hartel, founding Principal of peckvonhartel is a member of the Design Advisory Panel for all stages of WestConnex.
