Connecting the new motorway to State Highway 1
The new motorway will connect to the existing State Highway 1 network just north of the Johnstones Hill Tunnels and north of Warkworth between Hudson Road and Kaipara Flats Road. A southbound on-ramp and northbound off-ramp are also being constructed at Pūhoi.
As part of the work to connect the motorway, major road layout changes will be required on State Highway 1 at both ends of the project. These works are already underway and will continue through until the motorway opening.
Safety is our highest priority. The changes will be well sign-posted and a reduced speed limit will be in place for the duration of the works. Please keep to the temporary speed limit and don’t be distracted by work activity.
While we will try to limit disruption to traffic flows, road users should plan ahead and allow more time for their journey.
