The signage will operate automatically in times of flood and inform drivers if there is flooding and/or if the road has been closed, allowing them to modify their travel plans if necessary.
Two large LED signs, at Marsh Road and Lady Park are accompanied by four smaller prismatic ones – located at Heywood Lane, the top of Gumfreston Hill, Marsh Road, and Heatherton crossroads.
The two large LED signs can also be used to give traffic related information to the public on highways delays or local events which necessitate road closures such as Ironman, Tenby 10k, or CARTEN100.
Clr. Rob Lewis, Cabinet Member for Transportation and Major Events, said: “This signage is going to be a really valuable asset for motorists approaching Tenby, not only for when there is localised flooding, but also when there are large-scale events in the town.”
