Jane Dodds has raised concerns about road safety on the A470 at Libanus.
The Mid and West Wales MS asked at the Senedd yesterday (Tuesday) for a statement on the issue from Transport Secretary Ken Skates.
She said that many people will have driven across Bannau Brycheiniog through Libanus, which has no pedestrian road crossing.
Ms Dodds said: “Unfortunately, last week, there was a three-car crash at Libanus, highlighting the ongoing danger there.
“Firefighters needed to free a casualty, and local councillors have expressed severe concern about the daily risks faced by Libanus residents due to the 50mph speed restriction.
“Could I ask the Transport Secretary to detail interim safety measures and risk assessments for the A470 at Libanus?”
Leader of the Senedd, Jane Hutt, said the Welsh Government takes road safety very seriously.
She told Ms Dodds: “We routinely monitor speed data, along with personal injury collision records from the police, to inform us of the need for road safety improvements.
“We are updating the guidance on setting local speed limits to reflect Welsh Government policy, including the national roll-out of 20mph speed limits.
“When that new guidance is published, we'll review the speed limits across the trunk road network, including the A470 at Libanus.
“I think we have all driven through Libanus, and to hear of that collision brings the reality of this in terms of speed limits and enforcement, which is crucial.”
Ms Hutt encouraged Ms Dodds’ constituents to report any concerns directly to GoSafe, the Wales casualty reduction partnership, who are responsible for speed limit enforcement.
