Lane markings rubbed away M5 roadworks Southbound J7

Through the roadworks on southbound M5 at J7 and onwards the lane markings have washed away making it unclear where the lanes are. This has been visibly getting worse over the last couple of weeks.

Although this is a risk in itself, the main concern is where the lanes move back across and ‘merge’. While driving, although I was in the left hand lane, vehicles from the centre lane didn’t move across as expected and continued driving showing that the unclear markings are causing drivers to be unsure and could cause an accident.
