Background

The simultaneous M4 and M48 closures exposed a major weakness in cross-Severn travel. These bridges are vital, and full shutdowns disrupt commuters, businesses and emergency services. We need an independent review to improve maintenance, weather-closure protocols, contingency planning, and to invest in reliable alternative routes. Stronger infrastructure and clearer communication are essential to prevent future total closures and protect the region’s connectivity.
