A crash led to the closure of one the busiest routes into Cardiff on Saturday morning.
The incident, which happened at 04:40 GMT on the A470 at Coryton, left the roundabout on the M4 Junction 32 interchange shut for most of the morning.
It is not known if anyone was hurt.
Traffic Wales said it led to hold-ups, although a diversion was put in place. Traffic analysts Inrix said the road reopened at about 13:00 GMT.
South Wales Police said a single vehicle crashed on Coryton roundabout.
