New traffic arrangements will come into effect from Monday, May 23 as part of construction of the Puhoi to Warkworth motorway.
Northbound Hibiscus Coast Highway traffic will merge onto a small section of the new motorway, travel across the Arawhiti ki Ōkahu viaduct and exit at the new Pūhoi off-ramp onto Pūhoi Road.
Then on Sunday, June 12, SH1 will be closed between Silverdale and Pūhoi, from 9pm to 5am, as NX2 forms the second stage of the new road layout. A detour will be in place from Silverdale via Hibiscus Coast Highway.
From Monday, June 13, 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 merge onto the viaduct. SH1 traffic heading south towards the tunnels will merge onto the new on-ramp, just after Pūhoi Road.
Traffic will remain in one lane in each direction and motorists will not be able to drive on the Pūhoi viaduct (Arawhiti ki Pūhoi) until the rest of the 18.5 km motorway opens next year.
NX2 advises that should any of the above work be delayed due to weather or unforeseen circumstances, it will be rescheduled to the next available night.
