NZTA expects the changes will add fewer than five minutes’ delay to travel times.
It asks drivers to adhere to the temporary speed limits to keep all road users and contractors safe.
There will continue to be right in/right out access to all accessways until the turnaround facility at Oturoa Rd is operational. Construction of the turnaround facility is expected to be in operation within the next few weeks but could be delayed by weather and ground conditions.
The facility is designed to provide a safe place for road users to turn once the flexible median barrier has been installed in the area.
After the turnaround is operational, contractors will install the posts and wire rope for the median barrier. A further update will be provided before this work happens.
In the event of bad weather, the works will happen on the next fine evening.
The safety improvements project involves a new roundabout at the intersection of SH1 and Waitārere Beach Rd, stretches of painted wide centreline, roadside and median barrier and new turnaround facilities.
Construction of these SH1 improvements is being completed in stages. Construction of all the improvements is due to be completed by mid-2027.
