What we are doing
We have recently been working alongside the carriageways on the A4421 and the A421. We will shortly be constructing highway tie ins to connect new sections of road and the newly built bridges. The construction of the new highway will mean some utilities will need to be moved and reinstalled. To be able to carry this out safely a series of road closures will happen, on the A421 and the A4421. These works are essential to safely open the new section of road later this year. We apologise for any inconvenience this may cause and thank you for your patience while we complete this work.
To reduce impact, the A421 and the A4421 will not be closed at the same time. Our aim is to keep closures at weekends where possible
