Drivers heading along the M4 in Newport are facing serious holdups this morning after a lane was shut for maintenance work, with delays stretching beyond 20 minutes for some motorists.
The closure has triggered a significant build-up of traffic across the stretch, leaving commuters and travellers stuck in slow-moving queues as the work gets underway.
Anyone planning to use that part of the M4 is being advised to factor in extra time for their journey or consider alternative routes where possible to avoid getting caught up in the congestion.
No timeframe has been given yet for when the lane is expected to reopen, so delays could continue to stack up throughout the morning as traffic volumes increase during peak hours.
Drivers are urged to check live traffic updates before setting off and stay patient if they do find themselves caught in the queues.
