Which roads are affected?

We have identified 250 points on 152 stretches of road likely to have levels of NO2 (more than 40 µg/m3) in breach of legal limits beyond 2020 if no action is taken.

This includes busy stretches of local roads in all 10 local authority areas. It doesn’t include motorways and some major trunk roads, which are managed by Highways England.

We have asked government to give a clear instruction to Highways England to work to reduced NO2 to the same timescales.
