An upgrade and extension scheme to the road’s fibre optic communications network is planned in South and West Wales. Works are currently taking place on the A40 and the M4.
The works programme has overrun due to unforeseen circumstances. For more information on the latest traffic management see details below.
There will be a series of works at various locations on this section of the M4 from end of July to October. These will include overnight lane, hard shoulder and slip road closures when required. Further programme details will be published closer to the time.
