Vehicles are charged according to their size, which toll plaza they pass through, the time of the day and the day of the week.
If you’ve ever battled your way through the heart of Birmingham on a heavily congested M6 motorway, you’ll understand why traffic planners came up with the idea of a northern relief road for the city.
The route was conceived to take the weight off the M6, and ease journeys to London and the South East for long-haul traffic heading there from north west cities like Liverpool or Manchester.
Local traffic would continue to use the existing M6 motorway, as would traffic heading to other parts of the country such as North Wales or the West Country. The preferred route of the M6 Toll was published in 1986, splitting off from the M6 and rejoining it at junctions 3a and 11a - a distance of 27 miles.
