There will be a number of road closures in place on the M4 this week that are set to cause disruptions across south Wales.

These M4 closures come as a result of maintenance works set to be carried out during the week.

The closures are set to take place in various locations up and down the M4 including near Bridgend and Swansea.

These are the sections of the M4 that will experience road closures this week (March 25 to 31), according to Traffic Wales.
