Accident and broken down car causes A470 and M4 delays - live updates

An accident on the A470 and a broken down car on the A470 are causing Wednesday morning delays for commuters.

There are 30-minute delays on the M4 because a car has broken down on the eastbound carriageway near junction 28 Tredegar Park.

Traffic monitors are showing that traffic is queuing back to junction 30 at Cardiff Gate.

The accident on the A470 happened on the southbound carriageway near the Taffs Well Interchange. The vehicles involved were moved quite quickly to the hard shoulder, but the lanes closures caused delays around Upper Boat. Traffic had returned to normal for the time of day by 8.20am.
