Traffic management
• 4 March to Mid- May 2024 – surveys will take place on the underside of the bridges. We’ll work overnight when traffic flows are at their lowest. Lane + hard shoulder closures will be in place on the M4 to allow us to carry out the work safely. During the day the road will be open as usual.
• Mid-May to Mid-July 2024 – surveys will take place on the top of the junction/gyratory. We’ll switch to 24/7 working with lane closures and a reduced speed limit in place during the week. Lanes will be reopened for the weekends.
No work will take place over the Easter period and there will be no traffic management in place.
