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

Changed traffic conditions at the Warnervale interchange are continuing from Sunday night 21 October to Saturday morning 27 October, weather permitting.

Work to allow for the second stage of the Sparks Road bridge widening continues with building of work platforms under the Sparks Road bridge.

Partial closures of the M1 at the Warnervale interchange are required and a short detour will be in place along the existing entry and exit ramps at Sparks Road.

The detour is through the interchange only and a 40km/h speed limit will be in place. The existing 80km/h speed limit for the Tuggerah to Doyalson upgrade will remain in place on the M1.

Full closures and detours on the M1 Pacific Motorway northbound will be in place at night from Sunday 21 October to Saturday 27 October. The closures will be in place between 8.30pm and 4.30am from Sunday to Wednesday, between 9.00pm and 4.30am on Thursday and between 10.30pm and 5.30am on Friday, weather permitting.

In addition to this bridge work, single lane closures of the M1 will also be necessary in both directions in the first week of November and detours occasionally thereafter until December.

The M1 northbound lanes continue to be shifted to the right for about three kilometres from near the Alison Road overpass.

The northbound service centre ramps have been changed to suit this shift in lanes and access will be maintained at all times. Please follow the road signs. See a visualisation of the changed traffic conditions.


 

Project objectives

The M1 Pacific Motorway is an important link for motorists travelling 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 speed limit has been reduced to 80km/h and will be in place for the duration of the project.

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

The project is expected to be completed in 2020, weather permitting.
