A1(M) motorway

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.

Overview

Most of the English section of the A1 is a series of alternating sections of 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 summaries the road as motorways and non-motorways sections,
