Highways England said the 60mph speed limit had been place during peak times since the carriageway was converted into a smart motorway last year.

It is in force between junction 28 for Mansfield and 35A for Stocksbridge between 7am and 9am and 3pm and 6pm Monday to Friday.

“We’ve introduced signs so people using the road know the reason for the limit.”
