The M1 is Britain's first full-length motorway and possibly its most iconic. It is also one of the most important, forming the main road north from London, serving the industrial East Midlands and the most populous areas of Yorkshire before handing the north-south baton to the A1(M) near Leeds.
East Midlands Gateway 16 June 2017
Various changes to the road network around M1 junctions 24 and 24A to provide additional capacity to support the East Midlands Gateway project, a 700-acre logistics development. The new development will include a dedicated rail terminal and are located immediately adjacent to East Midlands Airport, and will have direct access to the trunk road network with a new junction on the A453.
The two main road works will be improvements to M1 junction 24A and the construction of a new A6 Kegworth Bypass.
M1 J19 Catthorpe 8 March 2017
Reconstruction of M1 Junction 19, the meeting place of the M1, M6 and A14. Provision of new free-flow links between M6 and A14. The plans as of Autumn 2003 will cause the realignment of the road between Catthorpe and Swinford away from the interchange, which in turn will mean the A14 from this interchange to Junction 1 will be upgraded to motorway.
The junction will carry the mainline of the M6 on to the A14, with sliproads between M1 south and M6, and between M1 north and A14.
M1 J32-35A Smart Motorway 13 January 2017
Upgrade of the M1 between junctions 32 (Thurcroft) and 35A (Hood Hill) to provide Smart Motorway technology. The upgraded road will have equipment to allow the use of variable speed limits and emergency refuge areas.
The hard shoulder will be converted to a permanent running lane for the full length of the scheme, meaning that this section of motorway will then have four running lanes and occasional emergency lay-bys but no hard shoulder. The Tinsley Viaduct will carry three traffic lanes plus hard shoulders.
M1 J19-16 Smart Motorway 11 April 2016
Upgrade of the M1 to provide Smart Motorway technology between Junction 16 (Kislingbury) and 19 (Catthorpe), with the stated aim of improving traffic flow, reducing congestion and increasing safety.
The upgraded section will operate All Lane Running, converting the hard shoulder to a permanent running lane. This will provide four lanes in each direction on this section of the M1, with emergency lay-bys to replace the hard shoulder.
M1 J28-31 Smart Motorway 28 March 2016
Upgrade of the M1 between junctions 28 (Pinxton) and 31 (Aston) to Smart Motorway. This will involve installation of electronic equipment to enable the use of variable speed limits and the installation of emergency refuge areas. It will also see the hard shoulder converted into a fourth permanent running lane. The completed motorway will not have a hard shoulder.
M1 J39-42 Smart Motorway 1 February 2016
Upgrade of the M1 between junctions 39 (Durkar) and 42 (Lofthouse) to Smart Motorway. Equipment will be installed to provide variable speed limits and emergency refuge areas along the full length of the road, and hard shoulder running will be possible to provide extra capacity at times of congestion.
This scheme replaces an earlier proposal to widen this section of M1 to full dual four-lane standard, which was withdrawn in favour of a series of Smart Motorway projects from Chesterfield to Leeds.
M1 Widening J29-42 (Chesterfield-Leeds) 29 December 2015
This scheme proposed on-line widening of the M1 between Chesterfield and the M62 (junctions 29 to 42) to dual-four lane standard. From Chesterfield to the M18 and between Wakefield and the M62 the route would be fully upgraded to dual-four lane with full hard shoulders. The remainder of the route (including the whole section through Sheffield) would be widened to dual four-lane without hard shoulders, but with a wide hard-strip and emergency refuges every kilometre. Advanced signal gantries would also be installed.
M1 J10A Improvement 6 November 2015
The aims of the scheme are to increase capacity and reduce congestion.
The scheme involves upgrading M1 J10a to allow traffic to flow freely between the M1 Spur and the A1081 Airport Way. The M1 Spur will be widened to three lanes each way, as will the section of the A1081 between J10a and the Capability Green junction, with a lane drop to two lanes each way running through the improved junction.
A 50mph speed limit will apply to the whole of the improved section when the works are complete.
M1 J24 Improvement 10 April 2015
Improvement of the A50 approach to J24 of the M1, currently a simple roundabout which forms a significant bottleneck.
The improvement will provide a path through the roundabout, controlled by traffic signals, to allow A50 to M1 South traffic to avoid the roundabout altogether and join the M1 at junction 23A.
M1 Widening J10-13 (Luton-Bedford) 7 October 2014
Plans for widening of the M1 between junctions 10 and 13 to dual-four lane standard have now been watered down to hard shoulder running. The original plan was for full on-line widening including improvements to junctions 11, 12 and 13. The amended scheme includes capacity improvements to junctions 11 and 12 only - these improvements are subject to separate statutory procedures, and so will commence at a later date than the HSR works, although still within the overall timeframe for the project.
M1 J19 Catthorpe Viaduct Replacement 29 September 2014
A scheme to replace the bridge carrying the southbound M6 over the M1. This whole junction is due to be remodelled to solve its endemic congestion problems, but has been further delayed by a government spending review. As a result it was decided that replacement of this bridge could not be put off any longer and will go ahead anyway. The existing bridge has been supported by temporary props in the southbound carriageway of the M1 for some years now.
