A1(M) junctions 6 to 8, Statutory Instrument Consultation (variable mandatory speed limits

Closed 9 Mar 2020

Opened 10 Feb 2020

Results updated 19 Nov 2020

We held a Statutory Instrument consultation for four weeks from 10 February to 9 March 2020, asking how the proposal could affect you, your organisation or those you represent. We have analysed the responses from our Consultation that ended on 9 March 2020 and published the report on the consultation



The A1(M) between junctions 6 and 8 in Hertfordshire is one of the busiest sections of the A1 between London and Leeds. The volume of traffic exceeds the road’s capacity during peak periods, resulting in congestion.

The number of cars using this route is likely to rise. These junctions are close to existing or proposed housing developments, and the area has the potential for up to 13,000 new homes by 2030. 

Highways England is planning to convert this section of the A1(M) to become a smart motorway, which will increase the road’s capacity by 50%. On completion, there will be a continuous three-lane motorway between junction 3 (Hatfield) and junction 9 (Baldock and Letchworth).

The section of the motorway between junction 6 and 8 will be ‘all lane running’, which means that the hard shoulder will be converted into a permanent lane for drivers to use, to help reduce congestion. Variable speed limits will be used to smooth the traffic flow.

The provision of an additional lane and introduction of variable mandatory speed limits will help to alleviate this congestion. It is expected that the smart motorways scheme will:

• increase motorway capacity and reduce congestion

• smooth traffic flows

• provide more reliable journey times

• increase and improve the quality of information for the driver (in relation to the operation of the motorway).

The use of variable mandatory speed limits is essential to achieving the objectives above. Through the introduction of technology, we aim to make best use of the existing road space.
