Don't forget Lincoln, Scunthorpe, Grimsby and Hull, which when added to Doncaster, exceeds Sheffield's population.
With the 50MPH for 20 miles of roadworks on the M1, it took me 2 hours to get from Sheffield to M1 J23A several weeks ago thanks to a broken down lorry on the M1. EMA can be a pain to get to from Sheffield in rush hour.
