Cardiff (Cardiff Daily) August 4, 2026 – Four Cardiff roads are set to return to 30mph after a review of the Welsh Government’s default 20mph scheme, with work due to start this week to put the new limits in place. The changes affect sections of Newport Road, Western Avenue, Ocean Way and Hadfield Road, while some school and sports-complex frontage remains at 20mph for safety reasons.

The Traffic Regulation Orders have now been legally sealed, meaning the legal process for the changes has been completed and implementation can begin.

Which roads are changing?

The review identified sections of four major routes for a return to 30mph. Cardiff Council said the changes were made after applying the Welsh Government’s revised guidance, which gives councils more flexibility to assess a road’s movement function, physical characteristics and the needs of nearby communities.

Newport Road: what will change?

Newport Road will return to 30mph, but the stretch outside St Illtyd’s Catholic School will stay at 20mph to protect pupils, pedestrians and other vulnerable road users.

Western Avenue: what will change?

A section of Western Avenue west of the Taff River Bridge will return to 30mph.

Ocean Way: what will change?

Ocean Way will return to 30mph from its junction with Beignon Close to Rover Way, except for the section alongside the Ocean Park Sports Complex, which will remain at 20mph.

Hadfield Road: what will change?

Hadfield Road will revert to 30mph between its junctions with Leckwith Road and Penarth Road.

Why did the council review the limits?

The changes follow public feedback submitted during the Welsh Government’s 2024 “listening” exercise on the default 20mph scheme, and Cardiff Council said it used the revised guidance issued last year to reassess roads.

The council said it received 933 requests for roads to be considered for a return to 30mph between April and the end of August 2024. Of those, 192 roads were reassessed before the four sections now selected for change were identified.

What did Dan De’Ath say?

Dan De’Ath, Cardiff Council’s Cabinet Member for Climate Change, Strategic Planning and Transport, said the review process had now reached the legal implementation stage. He said work would begin next week to introduce the 30mph limits on the four routes.

He also said the 20mph policy remains important in residential areas and around schools because lower speeds can reduce the risk and severity of collisions. He added that most of Cardiff’s 20mph roads will stay the same because they remain the right speed limits for those communities.

How does this fit the wider 20mph policy?

The wider policy context is that the Welsh Government’s default 20mph scheme has been under review, and councils were given more discretion to decide where higher limits are more appropriate. Cardiff Council said the revised guidance allows local authorities to judge roads by their function and setting rather than applying the same limit everywhere.

In practical terms, that means some major roads with heavier movement may be judged suitable for 30mph, while roads near schools and other sensitive locations can remain at 20mph. Cardiff’s latest changes reflect that split approach.

Background to the development

This decision follows the Welsh Government’s 20mph default scheme and the later review process that allowed councils to revisit specific roads. Cardiff residents and road users were invited to submit requests during the 2024 listening exercise, after which officers reassessed a larger pool of roads using the revised guidance and assessment tool.

The current change is therefore not a full reversal of the policy, but a targeted adjustment on selected routes where the council judged 30mph to be more appropriate.

What is the prediction for road users?

For drivers, the immediate effect will be a small increase in permitted speed on the four affected roads, which may slightly improve journey flow on those routes. For residents, pedestrians and parents near schools or busy public venues, the continued 20mph sections should still provide a lower-speed buffer where the council believes it is needed most.

For Cardiff as a whole, the likely result is a more mixed network: most 20mph roads will stay in place, while a limited number of major corridors are adjusted back to 30mph after local review.
