The Welsh Government has outlined next steps on 20mph in this press release: 20mph: Transport Secretary outlines plan for targeted change | GOV.WALES
Also the FAQ page has been updated to reflect this: Introducing 20mph speed limits: frequently asked questions | GOV.WALES
If you have suggestions (along with valid reasons) for why a road should be exempted from the 20mph national speed limit in Wales, please send them to TrafficManagement@blaenau-gwent.gov.uk please include name and address so we are able to register your suggestion.
We will log your feedback and review it once new exceptions guidance is available from the Welsh Government. We expect to receive this guidance by the summer.
We won’t be able to log any general comments about the 20mph National Policy, as that is a matter for the Welsh Government and Welsh Government Ministers.
If your feedback relates to a Trunk Road, these are not the responsibility of Local Authorities, so please email TrunkRoads20mph@gov.wales. More information on Trunk Roads is available on Datamap Wales.
