Overview
- Birmingham City Council confirmed it will replace existing 40mph limits with 30mph on 27 key routes under its Road Harm Reduction strategy.
- The rollout is expected to begin in early 2026, with no firm completion date set by the authority.
- The plan includes new roadside signage, additional speed and red‑light cameras, plus targeted police speed operations once the limits change.
- A-roads set for the lower limit include the A34 Walsall Road, A38 Bristol Road South and A45 Coventry Road.
- Hertfordshire’s B197 saw average speeds fall 14% after a similar change, though some local drivers there complain about added journey time and sudden implementation.
