For the last six years, there has been a succession of roadworks on this stretch of the motorway resulting in a string of complaints from Jim who has the Highways Agency number permanently 'logged in his phone'. With the latest roadworks again scheduled during the night when the motorway is at its quietest, Jim knows what to expect - 'you start seeing orange lights flashing and at 3 and 4 in the morning it's disco time'.

In the media storm that followed, the Highways Agency (HA) was heavily criticised for failing to prepare for snow and ice.

Highways Agency staff scour 450 CCTV cameras for problems on the M6, while Steve Taylor travels along the motorway at a steady 50mph on the lookout for potentially dangerous potholes.
