Making the road safer

Seventeen people died and 45 were seriously injured in crashes on SH1 between Wellsford and Warkworth between 2006 and 2015.

We’re planning improvements that will help in the short to medium term ahead of the completion of the Ara Tūhono Pūhoi to Wellsford project. Once completed, the second stage of the project (Warkworth to Wellsford) will travel west of the Dome Forest, completely separate to the existing SH1. The Dome Valley route will remain for local journeys, walking and cycling, and as an alternate route for traffic if the new road is closed for any reason.

What we are doing

This stretch of road is windy with poor visibility and steep slopes so we are limited to the type of improvements we can use. We know that the following safety improvements suit the road and are proven to save lives:

  • Putting in flexible median safety barriers to prevent head-on crashes and a wide centreline so there’s more space between oncoming vehicles.
  • Making road shoulders wider throughout Dome Valley so it’s safer to pull over, and so there’s more room for people who cycle.
  • Adding new right turn bays at L Phillips Road/Sheepworld and at the Top of the Dome rest area to make it safer to turn.
  • Replacing the northbound and southbound passing lanes at the top of the Dome Valley with wide shoulder so slow vehicles have room to pull over.
