Multi-vehicle crash blocking part of Auckland's Northwestern Motorway

Several vehicles have collided in the southbound lane of the northwestern motorway at 7.10am causing traffic to back-up.

A crash involving multiple vehicles is causing heavy congestion for commuters using the Northwestern Motorway.

The 7.10am crash blocked the right citybound lane just prior to the Lincoln Rd off-ramp on State Highway 16.

The crash vehicles were moved clear of lanes by 7.50am but NZTA says "heavy congestion" continues for citybound traffic through the Westgate area.

UPDATE 7:50AM
This crash scene has now been moved clear of lanes but has left heavy congestion citybound through the Westgate area on #SH16. Allow extra time. ^TPhttps://t.co/iLNXr2aTp1
