The M4 Prince of Wales Bridge had a two-lane closure for over five hours to allow National Highways to undertake repairs for a pothole yesterday evening (March 13).
The emergency repairs took place between junction 22 at Magor to junction 23 at Pilning Interchange in South Gloucestershire, and resulted in two of the three lanes being closed from just after 5pm until approximately 10.30pm the same evening.
A spokesperson for National Highways said they became aware of a carriageway defect just after 5pm on the eastbound carriageway.
