M1 Pacific Motorway, Weakleys Drive and John Renshaw Drive intersection upgrade

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

Updates and announcements

An environmental assessment has been carried out to identify potential impacts of the proposal and mitigation measures to be implemented. Stakeholders and the community are invited to comment on the environmental assessment by 7 December 2016.

Project background

The M1 Pacific Motorway is an important link in the National Land Transport Network and is part of the Sydney to Brisbane corridor, which is one of the busiest transport corridors in Australia. This intersection is the critical connection between the M1, Pacific Highway, New England Highway and local industrial and commercial precincts. 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.

The proposal is part of the Australian and NSW governments’ M1 Pacific Motorway Productivity Package which also includes upgrading the M1 between the Tuggerah and Doyalson interchanges and between the Kariong and Somersby interchanges.

In addition, planning is underway for a future extension of the M1 Pacific Motorway to Raymond Terrace. The intersection proposal considers the potential impact of a future extension.

Key features and benefits

The proposed upgrade provides the best overall balance between environmental, social, and technical considerations.

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 proposal 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

Environmental assessment

Roads and Maritime has carried out an environmental assessment to assess the potential environmental and social impacts of the proposal and identify activities to manage and mitigate these impacts.

The environmental assessment was carried out in consultation with a range of key stakeholders and considered feedback received from the community.

The investigations found the proposal is unlikely to have a significant impact on the environment with the application of a range of environmental mitigation and management measures.

Next steps

Stakeholders and the community are invited to comment on the environmental assessment by 7 December 2016.

Roads and Maritime will consider the feedback received when finalising the proposal.

The timing of construction is not yet confirmed.
