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

The contract for design work and the environmental assessment was awarded to Aurecon Australia in September 2015.

Comments on the proposed upgrade were invited in May and June 2015. Feedback received during the public display is informing the concept design and environmental investigations being carried out as part of the Review of Environmental Factors.

More information about the feedback received during the public display is available in the September 2015 Community consultation report (PDF, 1.7Mb).

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 includes:

  • Replacing the roundabout with traffic lights
  • Two through lanes on all approaches
  • Extending the two northbound lanes on Weakleys Drive to the Enterprise Drive roundabout
  • Right turn lanes on all approaches, including two from the M1 to John Renshaw Drive
  • Separate left turn lanes on all approaches
  • On and off-road provision for cyclists
  • Future provision for pedestrian crossings at the traffic lights when required.

The proposal requires road widening into the informal car park on the southwest corner of the intersection, which operates as a Driver Reviver facility during holiday periods. Roads and Maritime is investigating alternate sites for the Driver Reviver.

Key benefits of the proposal include:

  • Improved traffic capacity and safety at the intersection
  • Improved 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 Pacific Motorway to Raymond Terrace.

Next steps

Upcoming planning activities include:

  • Ongoing community and stakeholder discussions
  • Ongoing consultation with nearby businesses and residents
  • Preparing the concept design and review of environmental factors.

Subject to planning approval, the project would be completed by the end of 2019.
