Three lanes on a busy Auckland state highway were closed due to a crash this morning in bumper-to-bumper traffic.
Waka Kotahi NZTA announced at 12.10pm all lanes were now reopened on SH20 following the serious crash.
Motorists are still advised to allow for extra time travelling while delays in the area ease.
A police spokesperson said a vehicle flipped and came to a stop in the middle of the motorway heading west towards Queenstown Rd.
“Thankfully, the driver does not appear to have suffered any serious injuries.
“Traffic is backing up heading west and motorists are advised to expect delays.”
A video posted by Waka Kotahi showed a 5km gridlock across the Māngere Bridge behind the crash.
Three northbound lanes out of four on SH20 between the Neilson St on-ramp and Queenstown Rd off-ramp are closed as emergency services attend the incident.
Waka Kotahi first notified the public of the crash on the Southwestern Motorway at 10.45am.
The agency advised drivers to merge with extra care and delay their journey or consider using an alternative route.
Motorists are being warned to expect hazardous driving conditions.
