Project introduction

Safety improvements on State Highway 57 (SH57) from the SH1 intersection to Heatherlea E Road include a new roundabout at the Queen St/SH57 intersection, edge barriers, and wider centrelines. Plus, a review of the speed limits on SH57 from SH1 to Shannon.

Community engagement

During July and August 2020, we asked the public for feedback about the planned safety improvements and potential speed limits review on the section of SH57 between SH1 and Heatherlea E Road.

We’ll use the feedback provided to fine tune safety improvement plans and recommend whether a speed review will go ahead. If it does, we will then formally consult with the public on these speed limits.

Feedback has now closed. However you can see what others had to say on our interactive online map.

The draft engagement report is now available. This report reflects feedback on the infrastructure safety improvements on SH57. When the final version of the report is published, it will also include feedback we received on SH57 speed limits.

Proposed changes

We plan to make the following safety improvements:

  • Build a roundabout at the Queen St/SH57 intersection to reduce speeds and make it easier for you to choose the right time to enter flowing traffic.
  • Install stretches of edge barriers to prevent vehicles hitting something much less forgiving, like a power poles or drainage ditches.
  • Widen the centrelines to provide greater separation between vehicles. The existing road seal will be widened to accommodate the safety and infrastructure and improve the overall integrity of the road.

These safety improvements fit within the existing highway corridor and are a continuation of the safety improvements further north on SH57 completed in early 2020.

Community input will help fine tune the safety improvement designs. Construction is expected to begin this summer and take approximately 18–24 months to complete.

Safe speeds

Alongside these safety improvements, we are reviewing the current speed limits on SH57 between SH1 and Shannon to make sure they are safe and appropriate for this road. Regardless of the cause of a crash, speed is most likely to determine whether anyone is killed, injured or walks away unharmed.

Engagement with the community helps us get feedback and local knowledge on how you use the road and your concerns. The feedback gained helps us determine if and what proposed speed limit changes will be formally consulted on.

Previous safety improvements

We completed similar safety improvement work on SH57 between Heatherlea E Road and Graham Road in early 2020 as part of the SH57/SH1 to Shannon project.

Safety improvements on SH57 are part of the wider Ōtaki to north of Levin programme of works which included delivering the new Ōtaki to north of Levin highway within the next decade.
