M1 Junction 23a to Junction 25
Services: Planning & Controls
Value: 120 Million
The M1 is a strategic route that carries high volumes of heavy goods and other vehicles. Drivers currently experience congestion and unreliable journey times at busy periods and traffic is predicted to grow, particularly with the growth expected at East Midlands Airport.
The scheme in detail
In the 2014 Roads Investment Strategy, the M1 junction 23a-24 was confirmed as committed to extending the previously-announced M1 smart motorway junctions 24-25 improvement to junction 23a (East Midlands Airport).
The scheme will convert the M1 into a controlled motorway between junctions 23a and 24 and an all lane running smart motorway between junctions 24 and 25. In total we will be upgrading 7.5miles (12km), which is expected to begin main construction in early 2017 and complete in late 2018.
The scheme will involve:
- permanent conversion of the hard shoulder to create a fourth lane between junctions 24 and 25 and changing the junctions to accommodate this
- the introduction of variable mandatory speed limits with an associated enforcement/compliance system
- new CCTV cameras and electronic information signs and signals on gantries – these will show the variable mandatory speed limits and manage traffic flow and incidents
- emergency refuge areas throughout the length of the scheme
- the hardening of the central reserve and installation of a reinforced barrier to improve safety
- emergency roadside telephones (ERT) provided in within emergency refuge areas and in locations where the hard shoulder is retained
- queue detection and automatic signalling system, which provides queue protection and congestion management
- comprehensive low light pan-tilt-zoom (PTZ) CCTV coverage
