State Highway 1 road closure – Silverdale to Pūhoi

Kia ora neighbour,
We are writing to let you know about an upcoming full motorway closure on State Highway 1 (SH1) from
Silverdale to Pūhoi.
Details of the upcoming works
On Sunday 12 June, SH1 will be closed between Silverdale and Pūhoi from 9:00pm – 5am, as we form
the second stage of the new road layout. A detour will be in place from Silverdale via Hibiscus Coast
Highway.
From Monday 13 June 2022, northbound and southbound SH1 traffic will join Hibiscus Coast Highway
traffic on the new motorway alignment. Traffic heading north will exit from the Johnstone Hill Tunnels
and seamlessly merge onto the viaduct. SH1 traffic heading south towards the tunnels will merge onto
the new on-ramp, just after Pūhoi Road (See map of new layout below).
Should any of the above work be delayed due to weather or unforeseen circumstances, they will be
rescheduled to the next available night.
What this means for you
You may experience longer travel times while this work takes place, we advise planning ahead by
allowing extra travel time especially during the weekend and public holidays. To help plan for peak time
travel, visit the Waka Kotahi NZ Transport Agency journey planner at https://www.journeys.nzta.govt.nz
