20mph speed limits

The Welsh Government has announced a speed limit of 20mph for restricted roads in Wales (which came inforce from 17 September 2023).

20mph limits have been introduced in urban areas and include roads where streetlights are placed no more than 200 yards apart. See more details.

As a result of the change, the previous 30mph speed limits have been reduced to 20mph in most sites in Gwynedd. But with some roads where there is justification, the restrictions remain at 30mph and detailed work has been carried out to consider these locations by the Council's engineers.

We have also identified sites where the speed limits are currently 30mph, but which are not lit in accordance with national guidelines. In locations where it would be beneficial for the community to reduce the speed limits to 20mph, the Council has done so by introducing a traffic order.

Council officers engaged with Community/Town/City Councils and other stakeholders, and held a period to receive comments on the recommendations.

The map shows A, B and link roads Although roads within housing estates are not designated on the map, these changed to 20mph in accordance with speed lighting requirements.

More information about the Wales-wide scheme is available on the Welsh Government website.

20mph repeater sign requests

It is not lawful to install repeat signs or additional road markings for a 20mph speed limit on our network.

  • Repeat signs are only permitted for 30mph, 40mph and 50mph limits.
  • Once motorists pass the initial 20mph signs, they are expected to know the limit remains unchanged until they see new signs.
  • Painting 20mph roundels on the road surface is not permitted except at the start of the speed limit.

Speed humps

There is no current funding to construct speed humps or cushions on the network.

If requests are received Cyngor Gwynedd will:

  • Monitor the effectiveness of these current speed limits.
  • Address localised issues on their own merits if the new restrictions are deemed ineffective in specific locations.
