Project introduction

This project will see the creation of an entirely new section of SH3 north of Normanby. The new road will be built on the western side of the existing SH3. It will begin at the northern end of Waihi Rd and connect back to SH3 via an underpass below the Marton-New Plymouth Railway Line.

About the project

We’re realigning State Highway 3 near Normanby to improve safety and travel times on this busy and important route for the Taranaki Region. The community have advocated strongly for this project and we’re pleased that we can make it a reality.

Construction for the project has now started. In the coming months people will see the removal of the overbridge, realignment of the road and, once complete, will experience a shorter safer route with fewer curves and a highway that can support open road speeds.

The SH3 Normanby Realignment project aims to improve capacity and safety on this critically important route for the Taranaki region.

Benefits

  • The project represents a significant investment by the Transport Agency in the Taranaki regional roading network.
  • SH3 is an important route for people to travel to and from South Taranaki. This project will improve safety and route efficiency with a straighter and wider alignment, shortening the route length by half a kilometre.
  • SH3 is an important freight route. By making journeys shorter, we help to reduce the cost of doing business, and in doing so, grow Taranaki’s economy.
  • The new road will be built to 100km/hr standards and will better tolerate heavy vehicle traffic.
  • The existing highway route is via Ketemarae Road, Austin Road West and Boylan Road. The realignment means these roads will return to the local roading network managed by South Taranaki District Council.
  • A new 3.6km road built north from Normanby on the western side of the railway.
  • Demolition of the existing railway overbridge.
  • A new alignment without sharp curves.
  • 3.5m lanes, 1.5m shoulders, a 1400m northbound passing lane and a 1300m southbound passing lane.
  • The new road will link back to the existing state highway via a rail underpass.
  • A large section of the road is being lowered by seven metres for the underpass.

Project background

The SH3 Normanby Bridge Realignment project aims to improve capacity and safety on this critically important route for the Taranaki region.

This project was identified as a priority in the 2012-2015 Regional Land Transport Programme for Taranaki. On 29 June 2014 the government announced funding to accelerate five critically important regional state highway projects, drawing on the Future Investment Fund. One the five projects identified included the Normanby Overbridge Realignment.

This 4.2km section of SH3, from Waiha Road to Boylan Road, has poor alignment with a long history of incidents and serious accidents. This $11 million project will create a new straighter 3.6km road parallel to the existing SH3, which will reduce the risk of crashes. This new road will cut journeys by 600m which will reduce the cost of doing business, and in doing so, grow Taranaki’s economy.
