Auckland motorway crash: Truck flips spilling load, blocking Neilson St on-ramp, road closed

An on-ramp to the Southwestern Motorway is closed after a truck flipped spilling its load across the road.

NZTA Waka Kotahi is warning motorists using the southbound Neilson St on-ramp to expect delays after the crash around 11.55am.

It says motorists should avoid the route and to expect delays on Neilson St and around Ōnehunga.

A photo from the scene shows one of the large truck’s trailers on its side blocking one lane while debris is strewn across another lane around 20m from the wreck.
