There’s been a high number of crashes on State Highway 3 (SH3) between Waitara and Bell Block so we’ll be making some changes to help save lives. Over the next few years we’ll build roundabouts at high-risk intersections along the route and add sections of median barrier.
We’re in the final stage of construction of a safety enhancing roundabout and pedestrian underpass at the intersection of State Highway 3 (SH3) and Princess Street in Waitara.
Since February, workers on site have been busy completing work on Princess Street west. Over the last couple of months, they have completed stormwater work, excavated and rebuilt the road, completed the retaining wall on the pedestrian underpass, built the pump station that will pump water out of the underpass, and installed streetlights, footpaths, and traffic islands.
They are now ready to start on the final pieces of work for the roundabout and pedestrian underpass. This will include completing the roundabout itself, installing streetlights on SH3, and laying down asphalt.
To allow this work to take place, the temporary roundabout at the SH3/Princess Street intersection will be removed and the road reduced to one lane from the evening of Sunday 21 April until mid-June 2024.
Stop/go traffic management will control the flow of traffic through the intersection. The temporary 30km/h speed limit will remain in place.
Princess Street between Armstrong Avenue and SH3 will remain closed to traffic. Residents in the closure area will continue to have access to their property, and pedestrian access across the Princess Street intersection will remain open.
People travelling to or from Waitara from Princess Street will need to use Nelson Street or Bayly Street. Those wanting to access Princess Street west from Princess Street east (Tikorangi side) will need to use Bayly Street.
We anticipate that all work on the roundabout and pedestrian underpass will be complete by mid-June 2024.

What you can do to help keep everyone safe:
State Highway 3 is an important connection between New Plymouth, Waitara and beyond. It connects the Taranaki and Waikato regions, providing an important link for Port Taranaki, the New Plymouth Airport and major industries to the rest of the upper North Island.
Busy intersections, speed and roadside hazards like power poles and ditches cause safety issues on the road. There were 178 crashes on this route between 2014 and 2023. Six people died and 32 people were seriously injured.
Many of these crashes happened at intersections or involved drivers running off the road and hitting trees, power poles and deep ditches. There have also been head-on and side-on crashes.
Traffic is increasing on this part of SH3 which is causing delays, particularly for commuters. Anticipated residential and business growth in the area is expected to increase traffic which will create more congestion and make it difficult for drivers to get on the highway.
Following engagement with key stakeholders and the community, early safety improvements were carried out in February 2019. Further improvements including wide centrelines were implemented early 2021.
Roundabout concepts for the high-risk intersections at Princess Street, Waitara Road, SH3A (Mountain Road) and De Havilland Drive/Airport Drive were refined in mid-2021 to speed up construction.
This process was undertaken after investigations identified it would take a number of years to progress the roundabouts developed in 2018 to construction due to significant land, stormwater and costs associated with them.
An additional $53M in funding was secured in 2021 to deliver the project.
Construction on the roundabout at the intersection of Waitara Road and State Highway 3 is expected to get underway in early 2024.
The roundabout, as well as safety improvements to Raleigh Street, will make it easier for people to get on and off the highway.
To make the roundabout as safe as possible, the section of Raleigh Street between SH3 and Tate Road will become one-way, with traffic entering via a left turn off Tate Road. The layout of the intersection of Tate Road and Raleigh Street will also be changed from a four-way intersection to a T-intersection.
The combination of the roundabout and safety improvements to Raleigh Street and Tate Road, will make this intersection much safer for the Waitara community and everyone using the road.
Construction of the roundabout and pedestrian and cyclist underpass is progressing well with Stage 4 of construction about to begin. To date, some of the milestones include:
Construction of the roundabout and underpass is expected to be complete by mid-2024.
Watch the video below for a virtual flythrough of what the roundabout, underpass, and Manukorihi Park stormwater treatment wetland swale will look like once construction is complete.
CloseAn underpass is being built as part of the Princess Street intersection upgrade to provide safer access across the highway for pedestrians and cyclists.
Making sure people feel safe using the underpass has been a key priority of the design. New lighting will be installed at the intersection and the underpass will be lit day and night. The underpass has been designed so users can see right through it before entering. CCTV will also be installed for added safety.
Manukorihi, Ngāti Rahiri, Otaraua, Pukerangiora and Puketapu hapū (ngā hapū) have worked with Tihei Design and Workshop Studio to develop a cultural expression for the walls of the underpass and those leading up to it.
This work is the first part of a wider cultural narrative being developed for the road between Waitara and Bell Block.
The variety of cultural expressions for the corridor will give ngā hapū the opportunity to once again have a physical presence on the landscape and to depict and share their rich stories for the benefit of the community.
Each of the expression sites will be distinct, and to ensure connectivity with other sites along the corridor, novel design strategies will be used, similar to those depicted in the present Princess Street plans.

Flexible median barriers are a key part of this project.
Flexible median barriers put something between you and an oncoming car, truck, or motorcycle. This means that if someone loses control or drifts across the centreline, the result isn’t a deadly head-on crash.
Many of the crashes on SH3 between Waitara and Bell Block are head-on or at intersections so the combination of median barrier and roundabouts will significantly reduce the risk of these types of crashes.
Flexible median barrier will be installed along SH3 between Waitara and Bell Block in sections. The designs for the first two sections of flexible median barrier have now been confirmed. These designs were finalised following engagement with landowners and businesses along the route, emergency services, and representatives from the freight industry.
The first section of median barrier is complete and starts is from approximately 300m west of the intersection of SH3 and Bayly Street and ends approximately 40m east of the Mamaku Road intersection. This section of median barrier does not impact on access to properties or side roads.
The second section of median barrier will start approximately 40m west of the Nelson Street intersection and will end at the future Waitara Road roundabout. This will be installed once construction on the Waitara Road roundabout is complete. People driving on the road who need to turnaround will be able to use the Princess Street Roundabout or the Waitara Road roundabout.
Construction of the roundabout and pedestrian and cyclist underpass is being completed in four stages.
Stage 1 (March – May 2023)
During stage 1, we carried out site establishment works and implemented erosion and sediment controls. The wetland swale in Manakorihi Park which will treat stormwater runoff from the new roundabout was also constructed.
Stage 2 (May – November 2023)
During stage 2, we are constructing the underpass and the southbound lane for the roundabout.
Stage 3 (Late 2023 – early 2024)
During stage 3, we will construct the northbound lane of the roundabout and finish work on the underpass. We will also install the first stretches of flexible median barrier.
Stage 4 (mid 2024)
During stage 4, we will do some landscaping, complete the installation of cultural expressions, finish asphalt surfacing, road markings, install permanent signage and remove the traffic management at the site.
Following public consultation new safer speed limits were implemented on this stretch of road in December 2020, making the speed limit a consistent 80km along the entire route.
