The Brynglas Tunnels on the M4 are cleaned every month. A contra flow is put in place overnight on weekends and each side is completely closed off in-turn. The tunnels undergo a complete cleaning and general maintenance regime and all put back to normal for the next day.
Imagine the delays if this were done during the day!
