Plans for a new £8.7 million road layout scheme in Llanidloes and Llangurig are expected to be under review.

The Welsh Government has announced a freeze on new road building projects, whilst a review of highway schemes across Wales is carried out.

The schemes include introducing a northbound overtaking lanes off the existing Llangurig and Llanidloes roundabouts, costing £5.1 million and £3.7 million each.

A spokesperson for the Welsh Government said "it is likely this scheme will be subject to review".

"The list of schemes being reviewed will be confirmed by the Roads Review Panel within three months of its appointment with the Panel’s final recommendations within nine months. We expect to appoint the Chair and panel members shortly."

The Welsh Government’s recently published Programme for Government which shows how it will act to tackle the climate emergency. Deputy Minister for Climate Change Lee Waters told the Senedd: "Since 1990, Welsh emissions have fallen by 31 per cent. But to reach our statutory target of net zero emissions by 2050, we need to do much more. In the next 10 years, we are going to need to more than double all the cuts we have managed over the last 30 years, if we are going keep temperature rises within safe limits. That means changes in all parts of our lives. Transport makes up some 17 per cent of our total emissions and so must play its part.

"We need a shift away from spending money on projects that encourage more people to drive and spend more money on maintaining our roads and investing in real alternatives that give people a meaningful choice.

During a consultation earlier this year, the Welsh Government said it wanted to see road safety improved on these sections of the A470 after four collisions happened during the last five years were caused due to overtaking or poor visibility.

It said the road alterations would improve journey times between Builth Wells and Newtown by giving drivers the opportunity to pass slower moving vehicles safely.

The proposals have faced backlash from residents and community councillors who said he Welsh Government did not provide details on the plans before publishing the consultation which ended in April.
