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.
