PLANNED ROAD WORKS
Latest Traffic Management Report
The following are the latest planned traffic management on the M50 motorway. The information is updated on a regular basis by M50 Concession Limited.
Advance Notice: 2026 M50 Pavement Resurfacing Works
Essential pavement resurfacing works are planned on the M50 between Junction 10 and Junction 12, northbound and southbound, from Monday 18 May to Friday 12 June 2026.
M50 Concession Ltd will be carrying out pavement renewal works as part of the annual maintenance programme. These works are required to maintain the safety, performance and long-term condition of the motorway.
The works will take place overnight between 21:00 and 06:00, when traffic volumes are lower, in order to minimise disruption to road users.
Traffic management will be in place during the works, including lane closures and diversions where required. Temporary reduced speed limits will apply. Road users are advised to allow additional time for their journeys and to follow the temporary traffic management diversions in place.
As with all resurfacing works, the programme is weather dependent and may be subject to change due to operational requirements or site conditions.
We apologise for any inconvenience caused and thank road users and local residents for their patience and cooperation while these essential works are completed.
