The NZ Transport Agency advises motorists that a serious crash has blocked all north-bound lanes of State highway 1 on the North Shore, just after the Onewa Road off ramp.
All north-bound traffic is being diverted off the motorway at Onewa Road and traffic is building up back across the Auckland Harbour Bridge.
The Police serious crash unit is on the scene and it’s not known how long the motorway will be closed.
Motorists are advised to avoid heading for the Auckland Harbour Bridge and to use alternative routes north via the Western Ring Route on SH16 and SH18. Expect delays and avoid the area if possible.
