Highways England have a rolling programme of asset renewal, with reflective studs typically being replaced every 3-5 years. Highways Inspectors also carry out frequent inspections of the whole M5 carriageway and will assess and record any defects found.
Where studs are missing or damaged, Highways England arrange for their replacement as part of scheduled work schemes. In mid January 2020 overnight works took place on the M5 southbound carriageway between 11A and 12. 1446 studs were replaced.
