Background Information

Background Information

The M1 motorway is a heavily used strategic route linking London with the Midlands and the North.

Up to 150,000 vehicles per day use this section of the M1. We propose to improve approximately 50 miles of the length of the M1, between Leicester (Jct 21) and Chesterfield (Jct 30).

History of the scheme

In 2002, the Secretary of State for Transport announced plans to widen the M1 in the East Midlands, following the recommendations of the East Midlands Multi-Modal Study.

Preliminary studies were then carried out before the scheme was included in the national list of major projects in 2004. An engineering consultancy was then appointed to develop the project in more detail.

The Need for improvement

When it was built, this section of the M1 (between J21 and J30) would have been expected to carry up to 67,000 vehicles per day. It is now carrying between 103,000 and 153,000 vehicles per day.

The traffic flow map shows the existing flows, and the predicted traffic flows with and without improvement at the year 2030.

View Traffic Flow Map

The figures show that significant traffic growth is expected even if the motorway is not improved. The increasing congestion, however, would cause traffic to divert onto less suitable roads.

The increased traffic flows on the motorway after improvement would occur mainly as a result of traffic returning to the M1 from the local road network.

The project would:

  • Ease congestion
  • Improve journey times
  • Improve journey time reliability
  • Improve safety

Increasing capacity

There are a number of ways increased capacity can be provided. These include:

  • Widening
  • Junction improvements
  • Controlled motorway technology
  • Active Traffic Management technology
  • Climbing lanes
  • Auxiliary lanes
  • Free flow link roads
  • Ramp Metering

Respecting the Environment

We take our environmental responsibilities seriously and are committed to reducing negative impacts and, wherever possible, improving the existing situation. 
Our environmental interests cover:

  • Noise
  • Air quality
  • Water quality
  • Ecology and biodiversity
  • Landscape
  • Pedestrians, cyclists, horse riders and walkers
  • Archaeology, cultural heritage and protected sites of interest

We will carry out extensive environmental assessments for all aspects of the proposals and have already completed and published an Environmental Statement for the widening between Junctions 25-28.
