Scheduled maintenance
Like any major structure, the bridges need frequent maintenance to keep them in a safe and serviceable condition. Sometimes we need to close a bridge to keep road users and our team safe while we work.
The road surface on the M48 Severn Bridge is much narrower than a typical motorway, so there is less space for us to carry out maintenance. This means that we need to close the Severn Bridge more often than most other motorways.
We understand that these closures cause disruption to road users and local communities, and we’re striving to keep the bridges open as often as we can.
Our work isn’t always visible. We may be carrying out repairs underneath the road surface, or waiting for construction materials to dry or set before continuing our work.
