Police attended a collision on A4118, Gower, and closed a section of the road on Sunday evening.
In a statement just before 9pm, a South Wales Police spokesperson said: “There is a build-up of traffic in the area near the old Oxwich castle prior to the turning into Oxwich.
“Please avoid the area and use alternative routes where possible. Thank you for your patience.”
We have asked for further updates and will post them in the live blog below when they come in.
