A1(M) is the designation given to a series of five 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. Construction of a new section of A1(M) is currently underway between
Leeming and
Barton, with an anticipated opening in 2017. When complete it will link the Barton to
Washington section with the
Darrington to Leeming Bar section, forming the longest A1(M) section overall and reducing the number from five to four.
