A multi-vehicle crash involving a Porsche closed two lanes of the A3 Surrey-bound at the Tolworth junction.
One lane was later opened.
Queues were backed up to Shannon Corner following the accident which involved a blue Audi A1, a Citroen Berlingo, a black Porsche 911, a beige Volvo and a green Ford Mondeo.
A London Ambulance spokeswoman said two paramedic crews were sent to Tolworth roundabout shortly after 7am.
Between three and five cars were involved in the crash but only two people were treated for minor injuries, she said.
A man in his 40s was taken to Kingston Hospital.
