M4 delays as obstruction causes tailbacks - live updates

There's severe delays on the M4 in Cardiff due to an obstruction on the road.

The M4 westbound is partially blocked, resulting in slow traffic due to the issue.

The affected area is from junction 30 A4232 Pentwyn Link Road (Cardiff Gate) to junction 32 A470 Northern Avenue (Coryton Interchange).

Meanwhile, two of the busiest roads in Wales are also closed this afternoon after crashes have taken place. The first is on the A55, and causing "major delays".

Elsewhere, the A5 has been closed in both directions due to a crash.
