We are now at the stage where we need to complete the final layer of road surfacing at both ends of the project, this means there will be a series of road closures on SH1 in both the north and the south during March.

At the Northern Connection the project team will be undertaking pavement reconstruction and tie in works on SH1 between the Kaipara Flats Road / Goatley Road, and Hudson Road intersections. For safety reasons, a section of the road will be closed during the night while this happens.

When the closure is in place, there will be a detour around Warkworth (via Woodcocks or Hudson Roads, Carran, and Kaipara Flats Road). The detour will add up to 10 minutes travel time for road users, so we advise planning ahead for travel over this time. People travelling south, will be diverted via Kaipara Flats Road, Carran and Woodcocks Roads

• Sunday 12 to Thursday 16 March

• Sunday 19 to Thursday 23 March

At the Southern Connection there are full SH1 closures between Silverdale to Johnstones Hill Tunnels (JHT). Traffic will detour along Hibiscus Coast Highway (HCH). A stop/go operation will be in place on HCH to manage traffic safely, from 9pm to 5am.

Over Dimension vehicles will be assisted through both of these sites via our traffic management team by prior arrangement. Heavy vehicles are advised to take State Highway 16.

While all efforts have been made to limit disruption to traffic flows, we encourage you to plan your journey over this time and check the Waka Kotahi Journey Planner before heading out https://www.journeys.nzta.govt.nz/

These construction works are part of the final stages before the new motorway can be opened later this year. While this will no doubt impact travel, completion of these works takes us closer to opening the new motorway as soon as possible and we are all looking forward to enjoying a safer, more resilient, and reliable road with more consistent travel times.
