Auckland’s Southern Motorway has been partially blocked at Penrose after a vehicle struck a bridge, the second bridge-strike in the city today.

The collision happened about 1.05pm. Engineers have inspected the Penrose Rd bridge for any damage from the impact.

The left southbound lane between the Ellerslie-Panmure Highway and Southeastern Highway is blocked, Waka Kotahi NZTA said.

Southbound traffic has already backed up more than 2km past Ellerslie and Waka Kotahi said motorists should drive past with care and expect further delays.

Earlier today, a bridge-strike near Papakura cancelled all Southern Line train services between Homai and Papakua.
