This section runs through the Cambridgeshire countryside between Alconbury and Peterborough. It was officially opened by Lord Whitty on 31 October 1998, and is the most isolated of the motorway sections as it connects with no other motorway. It is designed to a noticeably high standard, 8 miles (13km) of it being four lanes from junction 14 at Alconbury to junction 16 at Norman Cross in each direction whilst the remainder has three lanes in each direction. It is managed by Road Management Services (Peterborough) under a DBFO contract with National Highways.

For centuries it was the only major route to get from London to York. In the "Road investment strategy" announced to Parliament by the Department for Transport and Secretary of State for Transport on 1 December 2014, planning will begin to upgrade the road in South Yorkshire to raise the last non-motorway section from Red House to Darrington to motorway standard. [34] Once completed, it will provide a continuous motorway-standard road between Blyth, Nottinghamshire and Washington, Tyne and Wear and will provide the North East and Yorkshire with full motorway access to London via the M1, M62 and M18. It will also improve safety along this route, as well as creating a new corridor to the North East, and reducing congestion on the M1 around Sheffield and Leeds. This is the only missing link of motorway on the strategic M1/ M18/ A1(M) route London to Washington.

A1(M) is the designation given to a series of four separate motorway sections in England. Each section is an upgrade to a section of the A1, a major north–south road which connects London, the capital of England, with Edinburgh, the capital of Scotland. The first section, the Doncaster Bypass, opened in 1961 and is one of the oldest sections of motorway in Britain. [1] Construction of a new section of A1(M) between Leeming and Barton was completed on 29 March 2018, a year later than the anticipated opening in 2017 due to extensive archaeological excavations. Its completion linked the Barton to Washington section with the Darrington to Leeming Bar section, forming the longest A1(M) section overall and reducing the number of sections from five to four. a b "A14 Ellington to Fen Ditton Scheme".

Plans to dual the single carriageway section of road north of Newcastle upon Tyne were shelved in 2006 as they were not considered a regional priority by central government. The intention was to dual the road between Morpeth and Felton and between Adderstone and Belford. [24] Junction 23 is where the M25 connects with the A1(M) just outside London.

It was also announced in 2014 that new technology would be implemented to bring the road to motorway standards, including detection loops, CCTV cameras and variable message signs to provide better information for drivers and active traffic management across Tyne and Wear, [34] while Junction 6 (Welwyn North) to Junction 8 (Hitchin) would be upgraded to smart motorway, including widening of a two-lane section to dual three lanes and hard shoulder running. [44] This plan to upgrade to smart motorway has now been cancelled. [49]Some sections of the A1 have been upgraded to motorway standard. These are known as the A1(M) and include:
