An oversized vehicle has hit an overbridge, blocking a southbound lane on Auckland's Southern Motorway.

Waka Kotahi NZTA said the lane will remain blocked for "some time this afternoon" after the incident at the Penrose Rd overbridge, with 45-minute delays for motorists heading south.

Structural engineers were on the way to the accident, according to the transport agency's latest update.

Southbound traffic has built up from Penrose, through Spaghetti Junction, and on to the Northern Motorway.

Waka Kotahi's traffic map shows southbound traffic is crawling at about 10km/h.

Motorists should delay their travel or use the Southwestern and Northwestern alternative routes.

Due to an overdimension vehicle striking the Penrose Rd overbridge, the left lane will remain blocked for some time this afternoon. Delay your journey or use an alternative route if possible as traffic is heavy in both directions. ^LB https://t.co/pi4aq5w9Cj
