Crash Blocks Lanes On Auckland's Southern Motorway

A truck carrying a digger in a trailer has hit the Penrose over bridge, blocking the middle and right hand lane of the southern motorway, southbound.

The arm of the digger has hit the over bridge, part of the Ellerslie Panmure southbound on-ramp, and a New Zealand Transport Agency spokeswoman said it needed to be assessed for damage, and is also closed.

She was unsure when it would reopen.

The accident, at 1.15pm, has caused congestion, with the NZTA asking motorists to avoid the area, and use the south western motorway as an alternative route.

Traffic is heavily congested from Market Rd.

There are no reported injuries and no other vehicles were involved, police said.

Emergency Services are on scene.
