Auckland's Northern Motorway is crawling between Oteha Valley and Lonely Track Rds northbound after an earlier crash.
The road has been cleared of debris following the incident but traffic is backed up to Albany.
The crash happened at Lonely Track Rd.
Meanwhile, congestion is building northbound at Esmonde Rd, between McClymonts and Greville Rds citybound and approaching the Harbour Bridge citybound.
Traffic on the Southern Motorway is heavy southbound between Newmarket and Tecoma St, and Highbrook and Drury. There are also heavy patches heading toward the city between Ellerslie and Market Rd.
It's also heavy between Great North and Lincoln Rds westbound on the Northwestern. There's a tail for the Northern Link citybound but traffic travelling south is flowing freely through Waterview Tunnel.
The Southwestern is heavy in sections between Walmsley and Massey Rds southbound, and Bader Dr and Walmsley Rd northbound.
