Roadside technology maintenance
From time to time, we need to maintain and upgrade roadside technology on our network. Here are details of where we are working and what this means for your journey.
Traffic management systems maintenance and upgrades - up to 1 March 2025
We will be implementing reduced speed limits on the following sections of our network while we undertake essential maintenance and upgrades to our traffic management systems. There will also be additional Traffic Officer patrols to help customers and respond to incidents.
Traffic management systems will not be available for short periods intermittently, during the times below.
If you are travelling on a smart motorway and need to stop, follow our advice on what to do in a breakdown or incident.
