M4 road closures this week affecting traffic in South Wales

These M4 closures come as a result of maintenance and environmental works and will affect sections including areas near the Vale of Glamorgan and Swansea. These closures come following a crash between a car and a lorry which caused the closure (both ways) of the M4 between junctions 22 (Prince of Wales Bridge) and 21 (Awkley) on Monday (December 4). Avon and Somerset Police described the incident on the M4[1] as a “serious injury collision”.
