M4 crash causes long delays and air ambulance called to separate collision – live updates

Those looking to get away for the bank holiday weekend and make the most of the warm weather are facing delays and transport disruption. The roads are starting to get busier and there are already some delays at the usual traffic hotspots on the M4.

The AA has estimated 23.4 million car journeys will take place on Friday. It highlighted that the M4 from London towards Wales will be a likely traffic blackspot.

A crash is already causing disruption on the M4. The two-vehicle collision has taken place on the westbound carriageway at Junction 44 for Lon Las.

Elsewhere, a serious crash has closed Wick Road at St Brides Major, with an air ambulance at the scene. A South Wales Police spokesperson said: “We’re at the scene of a serious collision on Wick Road, St Brides Major (B4265).

“The road is currently closed in both directions between St Brides Major and Wick.

“It is expected to remain closed for some time; please avoid the area and use alternative routes where possible. We’re grateful for your patience.”

As well as congestion on the roads, significant train delays are expected in Wales this weekend.

Transport for Wales is encouraging passengers to plan ahead as essential rail improvements take place across the Cardiff and valleys network.

Planned infrastructure improvements will close all lines through Cardiff Queen Street between Sunday, May 24 and bank holiday Monday, May 25.

To keep passengers moving, a combination of rail replacement buses and service diversions will operate across the local Cardiff and Valleys network.

Elsewhere, Network Rail has confirmed it is set to undertake work on the Severn Tunnel that the company says will “make the route more reliable for years to come”. The railway between Newport and Bristol Parkway or Filton Abbey Wood will be closed from Saturday.
