I have the M4 motorway in my Port Talbot back garden
Residents living directly beneath the elevated M4 in Port Talbot describe how the motorway has become part of their daily lives, providing shelter and shade while also bringing noise and litter from passing traffic. Built in the 1960s as Wales’ first motorway to relieve severe congestion, the structure cut through established neighbourhoods and displaced residents, later contributing to changes in compensation law. A 50mph limit introduced to reduce illegal nitrogen dioxide levels has lowered pollution and noise, while improvements in vehicles and home‑working have reinforced reductions. Despite its history and impact, some residents value the affordability and community the area still provides.
