Wet weather and a crash on the Kwinana Freeway have caused significant delays for commuters heading north into the city.
Just before 6.30am, a car collided with a motorcycle on the Kwinana Freeway near Beeliar Drive.
The right lane of the freeway was closed and the motorcycle rider was taken to hospital with leg injuries.
A Main Roads spokeswoman said the crash was cleared by 7.20am but the traffic remained, stretching back to Aubin Grove.
“All vehicles are now off the road, but the congestion goes back to Rowley Road and all the way through to Roe Highway,” she said.
“It’s a bad time of day for it and it’s also raining.”
