The County Council is reminding drivers to adhere to safe crossing times on the Holy Island causeway.
It comes after two vehicles were stranded over the weekend after becoming stuck in the incoming tide.

The council has now established the electronic signage on the island side of the causeway had been vandalised at some point over the past few days, which had reset the display showing safe crossing times.
During a site inspection, it was witnessed that the security padlock on the electronic sign had been damaged and the electronics tampered with, which in turn had caused an issue with the electrics inside causing the sign to reset.
As soon as the council was made aware of the signage issue yesterday (Sunday, March 8th) an engineer was sent to assess the signage and switch it off. It is due to be back on today (Monday, March 9th).
The Council is now looking into what improvements can be made with the temporary signage so this issue does not occur in the future.
However, there is a range of clearly displayed warning signs at both sides of the causeway reminding all drivers not to attempt the crossing if there is water on the road. Drivers should also be able to see the tide on the causeway.
Councillor Glen Sanderson, Cabinet Member for Local Services, said: “I’m extremely angry about this deliberate act of mindless vandalism which has caused these very unfortunate incidents and I hope that those responsible for the damage think about the lives they put at risk due to their stupidity.
“The dangers of attempting to cross Holy Island Causeway when the tide is coming in are obvious and we urge all drivers to check tide tables on-line for safe crossing times when planning their visit and to make sure they observe these safe times when crossing the causeway.”
