The M1 Upgrades will benefit commuters, holiday traffic, heavy vehicles and public transport users by:

  • improving traffic flow for better and more reliable trips
  • making it easier to move freight
  • allowing for predicted increases in traffic
  • providing safer access to and from the motorway.
