A470 Dolwen - Road marking renewal

Start Date: 19/05/2023 | End Date: 21/05/2023

Application of white lines and coloured surfacing in the centre of the carriageway between Llanidloes and Llandinam.

Work to carry out the application of white lines and coloured surfacing in the centre of the carriageway to a 0.5km section of the A470 eastbound and westbound carriageway at Dolwen (between Llanidloes and Llandinam) will commence on the 19/05/2023 for 2 nights.

The work will be carried out over 2 nights 20:00 – 06:00 under a full eastbound and westbound carriageway closure on the A470 at Dolwen from the access to Berth-Lwyd Farm to the junction near Upper Pen-Rhuddlan. 

The works are being carried out overnight during the weekend when traffic flows are lower, to minimise disruption.

Westbound traffic will be diverted via the northbound A470 to Caersws, then southbound on the B4569 via Trefeglwys to Llanidloes and eastbound to the B4518 Victoria Avenue to re-join the A470. The route is reversed for eastbound traffic.
