There will be a number of road closures in place on the M4 this week that are set to cause disruptions and delays for those travelling to and from Pembrokeshire.

These closures come as a result of works taking place in various locations up and down the M4 including on the Prince of Wales Bridge and in the Brynglas Tunnels near Newport.

These are the sections of the M4, according to Traffic Wales and National Highways, that will experience road closures this week (September 23 to 29).

While none of the closures are in Pembrokeshire itself, people travelling to and from the county could be held up.

This is the first time these kinds of works have been carried out on the Prince of Wales Bridge since it opened in 1996.

A lane on the M49 on the approach to the M4 at the junction 22 roundabout is also closed.

This is to help traffic move safely onto the Prince of Wales Bridge and into the roadworks.

These works are expected to be finished by the end of autumn.

But National Highways said: "But we’ll be doing everything we can to get the work done as quickly as possible."
