Realignment of State Highway 1 (SH1) Edendale to Start In Weeks

A contract has been awarded to build a bypass to take State Highway 1 (SH1) to the north-west side of Edendale, in Southland. Work is expected to start in coming weeks.

“Fulton Hogan has been awarded the $13 million construction contract and will get underway with site preparation works in June. This is one of the largest highway projects seen in Southland for many years,” says NZ Transport Agency Project Manager Jason Forbes.

“The safety and efficiency of the current section of highway is affected by a tight 45km/hour curve, three different speed limits, two rail lines that cross the highway to the Fonterra site and a steady stream of highway traffic past the local primary school, a lot of which are heavy vehicles.

The lack of safe passing opportunities is an issue on SH1 between Gore and Invercargill, causing frustration for drivers, and sometimes encouraging ‘risky’ overtaking manoeuvres. The new bypass will help address this problem with the introduction of a new north bound passing lane,” says Mr Forbes.

“Support from both Fonterra and the local community has been excellent. Their input into the project design has been invaluable and helped with the final design of the bypass. It is important that the realignment meets the needs of the Edendale community and the local dairy factory,” Mr Forbes says. A roundabout towards the southern extremity of the bypass will allow the highway to remain at 100km/hour, and connect to Edendale via Salford St and the Fonterra site.

Mr Forbes said strong growth in dairy and expansions at the Fonterra site mean there are a lot more milk tanker movements on this busy section of SH1.

Moving highway traffic away from the current location will improve safety, and bring considerable environmental benefits for the Edendale community, with less traffic noise and fewer vehicle emissions.

The new 2.6 kilometre long bypass will carry more than 5,000 vehicles a day, and take about two years to build.

This project also supports the Transport Agency’s goal of one network, delivering a joined up and seamless transport network of infrastructure and services that people and businesses can rely on every day.

Project benefits

Improved efficiency and safety on Southlands main freight route.
Road users would no longer have to negotiate the combination of tight curves, intersections and rail crossings on the current section of highway.
Redirects highway traffic away from residential properties and the local Edendale Primary School.
Provides a consistent speed across a modern new highway alignment.
Creates a more direct highway route between Invercargill and Gore.
Reduces highway traffic noise in the Edendale area.
Increased safe passing opportunities.
A stock and light farm vehicles underpass will see fewer highway crossings associated with the day-to-day operations of nearby farms.

Key features

A new highway alignment bypassing Edendale township and the Fonterra site.
Improved safety for highway users and the surrounding community.
A four legged roundabout with a design commensurate with the 100km/h speed environment of the two highway approach legs.
The highway will take a right angle route at the roundabout, with the two other legs servicing Edendale (Salford St) and the Fonterra site.
The new alignment will have a passing lane for northbound traffic.
A livestock and light farm vehicle underpass servicing local farms.

What can be expected?

Construction works are expected to start mid-2018 and continue through to 2020.
