THE A470 in the Brecon Beacons will be full closed during the day for a period of three weeks, starting later this month.

Motorists travelling through Powys via Llyswen can expect delays and diversions from Monday, September 23, while Welsh Water carries out a mains renewal.

The road will be fully closed outside Llyswen’s Griffin Inn from 8am to 6pm every day until Sunday, October 13.

Diversions will be in place and offer an alternative route via the A479 at Bronllys.

While the work will not affect Pembrokeshire, Carmarthenshire or Ceredigion, anyone planning on travelling to the Brecon Beacons in the coming weeks could be impacted.
