Traffic lights set for Vale of Glamorgan's Sully Island opposite…
An island opposite Weston-super-Mare, which has no roads or residents, is having traffic lights installed to stop people getting cut off by the tide.
Sully Island on the Vale of Glamorgan coast can only be reached by foot at low tide via a rocky causeway.
But over the years hundreds of people have been left stranded on the island when the tide comes in.
So the RNLI is trialling a set of traffic lights to warn visitors when they are likely to be cut off.
The lights are being installed today…
