A look at the detail of the smart motorway upgrade on the M1 between junctions 23a and 25.
The smart motorway opened on this section earlier this year.
This stretch of the M1 is part of a strategic route between London and the North carrying on average 130,000 vehicles per day between Leicestershire, Nottinghamshire and Derbyshire. Work began in March 2017 to tackle to the congestion and unreliable journey times that were regularly experienced on the M1 around East Midlands Airport.
In December 2018 the first phase of opening took place, introducing variable mandatory speed limits between junctions 23a and 24. This phase also saw the opening of the new lane in both directions between junctions 24 and 25.
During January and February, Highways England have been completing the testing and commissioning of the newly installed signs and signals between junctions 24 and 25. The successful completion of this work means we can be sure the technology is operating reliably and it was safe for us to open this stretch at speeds of up to 70mph.
As part of the smart motorway upgrade, the scheme has introduced new CCTV cameras and electronic information signs and signals on gantries, which show the variable mandatory speed limits and manage traffic flow and incidents. The scheme will also improve journeys through the capacity added, reducing congestion and making journeys more reliable on this vital route.
