A1(M) motorway

The four sections of the A1(M) highlighted against the other UK motorways

Looking northwards at Washington Services as the A1(M) approaches Junction 65

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.

There has been a proposal to renumber the section of A1(M) to M1 between Micklefield to Washington, making this section a northern extension of the M1.^[2]

Overview

Most of the English section of the A1 is a series of alternating sections of primary route, dual carriageway and motorway. From Newcastle upon Tyne to Edinburgh it is a trunk road with alternating sections of dual and single carriageway. The table below summarises the road as motorway and non-motorway sections.^[3] The non-motorway sections do not have junction numbers.

From London to Sunderland, 123.33 miles of the route are non-motorway while the remaining 145.38 miles are to motorway standards.

The motorway sections are discussed below.

A1(M) southbound at Sawtry.

This section which runs though the Cambridgeshire countryside between Alconbury and Peterborough first opened in 1998 and was officially opened by Lord Whitty on 31 October and is the most isolated of the motorway sections as it connects with no other motorway and is designed to a noticeably high standard, eight miles 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) Ltd under a DBFO contract with the Highways Agency.^[4]

This section opened in sections:

• Walshford to 49 opened in 1995
• Junctions 43 to 44 opened in 1999

When this section opened it ended at a temporary terminus south of the M1. There was a final exit into Micklefield Village for non-motorway traffic onto what is now the access road. During the first week of June 2009, Junctions 44 and 45 were renumbered to 43 and 44. At the same time the existing A1/A659 Grange Moor junction became A1(M) Junction 45.^[6] As a result many atlases show incorrect junction numbering for this stretch of motorway.

• Junction 46 to temporary junction at Walshford opened in 2005^[7]
• Junction 40 to south of 43 opened in 2005 & 2006

The northern section of the upgrade, bypassing Fairburn village, opened to traffic in April 2005 with a temporary connection with the existing A1 between Fairburn and Brotherton. The southern section, with a free-flow interchange with the M62 motorway, opened to traffic on 13 January 2006.

• Junctions 44 to 46 opened in 2009^[8]
• Junctions 49 to 51 opened in 2011 & 2012

Work began in March 2009 to upgrade the Dishforth to Leeming section to dual 3-lane motorway standard with existing connections being replaced by two new junctions. The Dishforth to Baldersby Section (J49 to J50) was completed in October 2011^[9] and the Baldersby to Leeming section (J50 to J51) was opened to traffic on 31 March 2012.

• Junctions 51 to 56 opened in 2017 & 2018 - there are no junctions 54 and 55

Work on upgrading the Leeming Bar to Barton section to three-lane motorway began in April 2014. Work was expected to be completed by summer 2017.^[10] In early 2017, the Highways Agency announced that the full opening would be delayed until December 2017.^[11] In the end, the motorway opened up on 29 March 2018, making the A1 continuous motorway standard from Darrington, West Yorkshire, to Washington, Tyne and Wear, though residual works were still to be completed.^[12]

• Junctions 56 to 59 opened in 1965
• Junctions 59 to 63 opened in 1969
• Junctions 63 to 65 opened in 1970
