Multi-car crash on Narrows Bridge sparks peak-hour chaos, Tonkin Highway also hit by traffic delays

A multi-car crash on a busy Perth freeway is already causing traffic chaos for commuters.

Several cars collided around 6.30am on the northbound side of Narrows Bridge, blocking the two left lanes.

Police motorcycles and towing services attended the scene

Main Roads WA said the crash had been cleared at 7.30am but warned heavy traffic congestion remain on approach to Mill Point Road.

A crash southbound on Tonkin Highway is also backing up traffic near the exit to Dunreath Drive and Perth Airport.

The left turn lane to those exits is blocked as tow trucks work to move the cars.

Main Roads WA said traffic was heavy on approach back to Guildford Road and urged drivers to merge safely.

Drivers are urged to exercise extreme caution due to the extra congestion.

More to come.
