Delays expected after three-vehicle Southwestern Motorway crash

Motorists are facing peak-hour delays on two Auckland motorways after a crash on one and debris blocking another.

A three-car crash on State Highway 20 this morning just after 6am blocked the right southbound lane before the Walmsley Rd overbridge.

The New Zealand Transport Agency said the crash has now been cleared from the lanes.

But delays were expected while congestion eased, it said.

Earlier, police said motorists were advised to expect delays or seek an alternative route.

No injuries were reported.

Meanwhile, NZTA reported at 8am that debris was blocking two lanes northbound after the Mt Wellington Highway on SH1.

“Pass with care and expect delays.”
