M4: Newport section reopens after death crash at Brynglas tunnels
The M4 eastbound has reopened at Newport after an earlier crash in which a 67-year-old man died.
The motorway was shut for around six hours leading to five-mile (8km) queues of traffic.
Traffic congestion in the section up to the Brynglas tunnels where the incident took place had eased by Friday afternoon.
Traffic had been queuing as far back as Cardiff Gate as diversions were put in place around Newport.
Gwent Police said the crash involved one vehicle, a Peugeot 308 saloon, which collided with a wall and an electrical sub-station at the entrance to the Brynglas tunnels at around 03:05 GMT.
The driver, who was from the Cardiff area, was recovered from the car but was pronounced dead at the scene.
The eastbound carriageway was closed so the vehicle could be recovered and a structural assessment of the sub-station and tunnel carried out.
The carriageway eventually reopened at 08:45 GMT.
Traffic Wales said during the closure there was a five-mile queue of traffic waiting to leave the M4 to use the diversions with vehicles backing up to Cardiff Gate, J30.
Traffic was also said to be heavier than usual on A48 Southern Distributor Road Eastbound between M4 J28 / A4072 (Tredegar Park) and M4 J24 / A449 (Coldra) due to the diversion.
Anyone who may have witnessed the collision is asked to contact Gwent Police on 101.
