Below, are all the upcoming weekend closures up to mid May 2021, as part of the M4 J3-12 motorway upgrade. Weekend closures are used to complete work that would not be possible otherwise e.g. extensive surfacing, complex work across multiple lanes and switching traffic management layouts. Closures keep drivers and our workers safe whilst upgrades take place. These closures are subject to change so always make sure to check before you travel.
