What percentage of Wales road network will fall within the planned 20mph speed limit?
Answered by Deputy Minister for Climate Change | Answered on 09/09/2021
There are a total of 34,850km of public road in Wales. In terms of the 20mph project, it is anticipated:
- 60% will be out of scope as it has a speed limit of 40mph or above.
- 35% will automatically change from 30mph to 20mph (existing 30mph, not A or B classified).
- 5% will be reviewed through an exception process (existing 30mph, A or B classified), of which a small proportion would be expected to be classed as an exception to remain at 30mph. The majority will become 20mph.
- <1% is already 20mph
It is anticipated, the changes will therefore affect close to 40% of the total length of Wales road network.
