Ara Tūhono – Pūhoi to Warkworth

LATEST UPDATES

State Highway One (SH1) – Road closures –Southern Connection & Northern Connection – February and March 2023

At the Southern Connection there will be extended road closures at the Johnstone Hill Tunnels, as well as the likelihood of additional road layout changes.

Overnight closures are planned in both directions during February and March to complete the final road surfacing, chip sealing, barrier installation, line marking and signage.

Northbound SH1 closures between Silverdale to Johnstones Hill Tunnels (JHT). Detours will be in place via Hibiscus Coast Highway, from 9pm to 5am.

  • Sunday 12 to Thursday 16 February
  • Sunday 19 to Thursday 23 February
  • Sunday 26 February to Thursday 2 March
  • Sunday 5 to Thursday 9 March

While the northbound closure is in place, traffic will detour along Hibiscus Coast Highway (HCH). A stop/go operation will be in place on HCH to manage traffic safely.

Over Dimension vehicles will be assisted through the site via our traffic management team.  Heavy vehicles are advised to take State Highway 16.

Southbound SH1 closure between Pūhoi to the JHT.  Detours will be in place via Hibiscus Coast Highway, from 9pm to 5am.

  • Wednesday 15 February and Thursday 16 February
  • Sunday 19 to Thursday 23 February
  • Sunday 26 February to Thursday 2 March
  • Sunday 5 to Thursday 9 March
  • Sunday 12 to Thursday 16 March

Additional to these night-time road closures, there may be new road layout changes needed in the south to complete the final tie-in works around the JHT.  We will update you once we have more information. So keep an eye on here or follow our Facebook page @aratuhonopuhoitowarkworth.

These works are being coordinated alongside closures at Dome Valley for maintenance as both teams are again working together to ensure that we capitalise on these closures and get as much work done with the least possible disruption.

As the Dome Valley works will close SH1 from Hudson Road, Warkworth through to Wellsford our Northern Connection team will be working a few nights within their two-week closure to complete paving and other finishing works. Our stakeholder team will liaise with any directly affected neighbours.


PROJECT OVERVIEW

The Pūhoi to Warkworth project will extend the four-lane Northern Motorway (SH1) 18.5km from the Johnstones Hill Tunnels to just north of Warkworth. It is the first stage of the Ara Tūhono – Pūhoi to Wellsford project, and will open sometime in 2023.

Ara Tūhono means a connecting pathway (Ara meaning pathway/passage and Ara Tūhono means connecting or linking one part to another).

The highway will be built to the west of the existing SH1 and bypass Warkworth on the western side. It will be a four-lane dual carriageway, separated by a central median with a safety barrier.

Key benefits of the new route include improved safety and connectivity, more reliable journey times and a better freight connection for the Northland region.

P2Wk Route Map

The Pūhoi to Warkworth project is a PPP (Private Public Partnership) between the Government and a private consortium, the Northern Express Group (NX2).

While the NX2 private-sector consortium will be responsible for financing, designing, building, maintaining and operating the motorway for up to 25 years, the motorway will remain a public asset.
