M1 Pacific Motorway Upgrades - Weakleys Drive and John Renshaw Drive intersection

Roads and Maritime Services will upgrade the M1 Pacific Motorway at the Weakleys Drive and John Renshaw Drive intersection at Beresfield. The upgrade involves replacing the existing roundabout with traffic lights to improve traffic flow, travel times and safety for motorists.

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

An environmental assessment has been carried out to identify potential impacts of the upgrade and mitigation measures to be implemented. Stakeholders and the community were invited to comment on the environmental assessment in November and December 2016.

We are considering the feedback received in finalising the proposal.

Project background

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

The Weakleys Drive and John Renshaw Drive intersection is the critical connection between the M1, Pacific Highway, New England Highway and local industrial and business areas. The existing two lane roundabout is used by about 4000 vehicles per hour in peak periods and cannot effectively cater for the current level of demand.

Planning is also underway for a future extension of the M1 Pacific Motorway to Raymond Terrace. The Weakleys Drive and John Renshaw Drive project considers the potential impact of a future extension.

This project is part of the M1 Upgrades, which also includes upgrading the M1 between the Tuggerah and Doyalson interchanges and between the Kariong and Somersby interchanges. 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

Key features include:

  • replacing the roundabout with traffic lights
  • two through lanes on all approaches
  • additional turning lanes on all approaches, including two right turn lanes from the motorway to John Renshaw Drive
  • extending the two northbound lanes on Weakleys Drive from the traffic lights to Enterprise Drive
  • upgrading the existing left turn slip lane from John Renshaw Drive to the motorway to improve safety
  • an additional left turn lane from John Renshaw Drive to the motorway to manage times of peak holiday southbound traffic
  • on-road provisions for cyclists.

Key benefits of the upgrade include:

  • improved traffic capacity and safety at the intersection
  • improved freight and traffic flow and more reliable travel times through the intersection
  • compatibility with future upgrades across the road network, including the proposed extension of the M1 to Raymond Terrace.

Next steps

The environmental assessment for the upgrade was finalised in February 2017. The upgrade has been approved and will proceed into detailed design, with construction to start in 2018.

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