Auckland’s Northern Motorway closed between Northcote and Onewa Roads from 10.30 am

|

The NZ Transport Agency has closed Auckland’s Northern Motorway, State Highway 1, due to flooding, southbound between Northcote Off-ramp and Onewa On-ramp. A detour is in place via local roads. Motorists are advised to expect significant delays while the high tide passes.

Please avoid the area and postpone any non-urgent travel. Consider using the Western Ring Route (SH18/SH16). SH1 was down to one lane earlier today due to flooding of the southbound lanes.

Wider driving advice

There is surface flooding in many places across the country today, in towns and on rural roads and highways. The Transport Agency asks everyone to slow down, watch for flooding signage or water on the roads, remember to leave longer following distances between cars and drive with care and patience. Posted speed limits may be too high in rain and flooding conditions with poor visibility so people need to err on side of caution.
