WestConnex toll road

Client // NSW Treasury

GTA Office // Sydney and Brisbane

Since 2016, GTA has been working with the NSW Treasury to provide independent traffic forecasts to support the equity sale of the Sydney Motor Corporation (SMC), the constructor and concession holder of all three stages of WestConnex.

Currently the largest infrastructure project in Australia, the $16.8 billion WestConnex toll road will be built in Sydney to connect the existing M4 and M5 freeways, which link Sydney’s west and south-west with the CBD. The 33km motorway system will form a vital part of Sydney’s future integrated transport plan and support long-term economic and population growth.

Specialists from GTA’s Transport Analytics and Transport Advisory teams harnessed collective skills in forecasting demand for toll roads, bringing to bear risk analysis, emerging sources of traffic and travel data, and spatial analytics to provide independent traffic forecasts of WestConnex for bidders’ valuations.

In August 2018, the NSW Government announced Transurban as the successful buyer of 51% of the Sydney Motorway Corporation. The WestConnex project comprises several major components and is scheduled to be completed by 2023.
