A wnaiff Llywodraeth Cymru adolygu cyflwr y marciau ffordd ar yr M4 i'r ddau gyfeiriad rhwng Cyfnewidfa Coldra a'r M48, ac ymgymryd ag unrhyw waith adfer angenrheidiol i adfer llinellau sydd wedi pylu neu sydd ar goll lle bo angen er mwyn sicrhau diogelwch ar y ffyrdd a llinellau clir rhwng lonydd?
The Welsh Government routinely monitors the condition of the motorway and trunk road network, including road markings, through its established inspection and maintenance arrangements. Safety is our first priority, and where inspections identify faded or missing markings which may affect road safety or clear lane delineation, appropriate remedial works are considered and programmed.
Officials will ask the South Wales Trunk Road Agent to review the condition of the road markings on the M4 in both directions between the Coldra Interchange and the M48 as part of these arrangements. Any works identified as necessary will be prioritised and delivered in line with safety requirements, network needs and available maintenance programmes.
