The NZ transport Agency says there is a danger of surface flooding on the Auckland motorway network due to severe storms sweeping across the city.
“The risk of flash floods on the network means that people need to drive with extreme care, use their headlights and watch their following distances,” says the NZTA’s acting State Highways Manager for Auckland and Northland, Steve Mutton.
Mr Mutton says the closure of State Highway 18 (the Hobsonville Motorway) in north-west Auckland means congestion is building up on other parts of Auckland’s network.
“People should consider whether their travel is necessary until conditions improve. If they are driving, we ask them to do so with patience – conditions are extreme, unpredictable, and difficult.”
SH18 is closed between Brigham Creek Road and Greenhithe Road in both directions. It was closed just after 1.30pm. Mr Mutton says it will remain shut until the NZTA has assurances it is safe to be re-opened and it will keep people updated using motorway electronic signs.
