  • Northbound: Closed Tuesday 12 to Thursday 14 August, 9pm to 5am





The closures are part of NZTA’s general maintenance schedule.


Dates may shift depending on weather.


Affected ramps include:


  • Silverdale southbound on-ramp
  • Oteha Valley Road southbound off-ramp
  • Oteha Valley Road northbound on-ramp
  • Silverdale northbound off-ramp
  • BP Dairy Flat ramps (no public access during works)


Recommended detours:


Use Twin Coast Discovery Highway, Dairy Flat Highway and Oteha Valley Road.





Locals travelling at night, including shift workers, airport-bound drivers or anyone heading to Auckland after hours, may need to allow extra time.


Some ramp restrictions may begin earlier than 9pm.


This work coincides with full closures for the Penlink project.


There will be no through access on SH1 in either direction from 10 to 14 August, 9pm to 5am.
