THREE-WAY traffic lights will cause delays for Powys motorists for the next month on one of the county’s busiest roads.

Repairs to the highway drainage system along the A470 between Llanidloes and Llangurig will result in traffic lights coming into force from Monday (October 31), with work set to end on November 25.

Traffic Wales tweeted: “Repairs to highway drainage along A470 Llangurig to Dolhelfa.

“3-way traffic lights to be in place at the roundabout from October 31-November 25.”
