Structural engineers are assessing the Brynglas Tunnel on the M4 South Wales following a major fire in the Westbound bore yesterday.
The fire occurred on a lorry during yesterday’s rush hour causing major traffic between Newport and Cardiff and causing the M4 between junctions 24 and 28.
The Eastbound tunnel has now re-opened with a contraflow in place.
“Our multiagency team are working around the clock to reopen the westbound tunnel,” said a Welsh Government spokesman. “It is clear that there remains considerable work to clear debris ad conclude the structural assessment to ensure the tunnel is safe for use.”
“We will continue to provide regular updates and work as quickly as possible to resolve the situation. We would appreciate your continued patience and understanding at this time.”
Investigations are ongoing into the cause of the blaze and a Welsh Government spokesman said exact details on how long the westbound tunnel would be closed for and the extent of the damage is still being accessed.
