The man who died after a road traffic collision on the M4 at the entrance of the Brynglas Tunnels on Friday has been named as 67-year-old David Archer, from Cardiff.
Police are continuing to appeal for witnesses to the collision, which occurred in the early hours of Friday morning. It involved a dark grey Peugeot car which collided with a wall and an electrical sub-station.
CCTV shows a number of motorists stopping at the side of the vehicle immediately after the collision, officers are particularly interested in speaking to these people. They include heavy goods vehicle drivers, and one man who actually got out of the passenger side of a passing vehicle and walked over to have a look inside.
Anyone who may have witnessed the collision is asked to contact Gwent Police on 01633 642404.
