A main road out of Swansea is closed after a collision involving a motorbike and a car.
The A4067, the road into the Swansea valley, is shut between the M4 motorway junction 45 at Ynysforgan and Glais after the crash at about 16:00 GMT.
South Wales Police remain at the scene and the road will stay shut as officers investigate the incident.
In a separate crash, a man was taken to hospital after a "serious accident" on the A4118 at Upper Killay at 17:00.
The South Gower Road has now reopened but police have asked motorists to "be patient" as they probe the earlier crash near Ynysforgan.
The accident caused rush hour tailbacks in both directions on the M4 and traffic is still slow on the B4603 in Ynysforgan.
