A new speed limit has come into force on five major roads and motorways in Wales.

50mph limits will now affect parts of the M4, A470 and the A494 in an attempt to cut pollution.

Emissions could be reduced by this amount from the changes.

The measures are part of a new £20m Air Quality Fund to reduce nitrogen dioxide (NO2) levels on roads where levels are currently above legal limits. The 50mph speed limits are expected to reduce emissions by up to 18%.

The speed limit will come in on the following roads:

  • A494 at Deeside
  • A483 at Wrexham
  • M4 between Junctions 41 & 42 (Port Talbot)
  • M4 between junctions 25 & 26 (Newport)
  • A470 between Upper Boat & Pontypridd

The Environment Minister said the changes will be "for better health and well-being".

We will encourage local authorities to introduce Clean Air Zones, where evidence suggests they are needed to reduce harmful emissions, as well as launching a new website which allows people to check the air quality in their area.

Delivering clean air in Wales is one of my key priorities. I am confident the measures I am announcing today will help support the changes we need to make in Wales to deliver cleaner air.

– Hannah Blythyn, Minister for Environment
