Information Signs

The table below shows current roadside message displays on Wales' motorways and trunk roads. We plan to extend this feature, but at present messages are only available on a limited number of roads. Some local authority and Highways Agency (England) signs are also shown, where available. Please note that signs currently blank are not displayed.
