M1 Pacific Motorway Upgrades – Tuggerah to Doyalson

Roads and Maritime is upgrading the M1 Pacific Motorway between the Tuggerah and Doyalson interchanges to improve traffic flow and safety. The upgrade involves widening the motorway to provide three lanes in each direction and rebuilding the roadway to provide a smoother and more durable surface.

This project is one of three M1 Upgrades, providing a better and more reliable journey on one of Australia’s busiest roads. 

Updates and announcements

The major construction contract has been awarded to CPB Contractors Pty Limited.

Geotechnical investigations are being carried out on the M1 Pacific Motorway at St Johns Road, Jilliby and Sparks Road, Warnervale. More information on these investigations can be found in the community notification (PDF, 402Kb).

We will continue to provide more information to residents and stakeholders as the project progresses.

Project objectives

The M1 Pacific Motorway is an important link for motorists traveling between Sydney to Brisbane, which is one of the busiest transport routes in Australia.

The 12 kilometre section between Wyong Road, Tuggerah and the Doyalson Link Road is currently two lanes in each direction. It has the most traffic of the remaining four lane sections between Sydney and the end of the motorway at Beresfield. This motorway is used by through traffic and traffic north of Wyong accessing the Central Coast.

The upgrade will cater for the increase in traffic demand from growth in the Central Coast, Hunter and North Coast.

This project is part of the M1 Upgrades, which also includes upgrading the M1 between the Kariong and Somersby interchanges and at the Weakleys Drive and John Renshaw Drive intersection. The M1 Upgrades make up the $391.6 million M1 Productivity Package funded by the Australian and NSW governments to improve traffic flow and safety on the M1.

Key features and benefits

The upgrade includes:

  • widening a 12 kilometre section of the motorway to provide three lanes in each direction between Wyong Road at Tuggerah and the Doyalson Link Road
  • rebuilding a nine kilometre section of the motorway between Wyong River and the Doyalson interchange to improve the road surface
  • improving road drainage for safety during wet weather
  • providing safety and capacity improvements to key motorway interchanges at Warnervale and Doyalson.

Key benefits include:

  • increased traffic capacity along the motorway
  • better travel times for motorists
  • improved road safety
  • smoother road surface.

Next steps

The construction contract was awarded to CPB Contractors Pty Limited in February 2017.

Construction is expected to start this year, for completion in 2020.

We will continue to keep stakeholders and the community informed as the project progresses.
