A1 Road (Great Britain) - A1(M)

A1(M)

Some sections of the A1 have been upgraded to motorway standard. These are known as the A1(M) and are part of European route E15. These include:

M25 to Stotfold

The M25 to Stotfold section is 23 miles (37 km), and was constructed between 1962 and 1986. The main destinations are Hatfield, Welwyn Garden City, Stevenage, and Letchworth It opened in five stages: junctions 1 to 2 in 1979; 2 to 4 in 1986; 4 to 6 in 1973; 6 to 8 in 1962; and 8 to 10 in 1967.

Alconbury to Peterborough

The Alconbury to Peterborough section is 14 miles (23 km), and opened in 1998.

Doncaster bypass

The Doncaster bypass opened in 1961 and is one of the oldest sections of motorway in Britain. It is 15 miles (24.1 km) long, and runs from Blyth to Carcroft.

Darrington to Leeming

The Darrington to Leeming section was constructed between 1995 and 2012. It is 34 miles (55 km), and opened in sections:

• Walshford to 49 in 1995
• Junctions 43 to 44 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 43 and 44. At the same time the A1/A659 Grange Moor junction became A1(M) Junction 45. As a result many atlases show incorrect junction numbering for this stretch of motorway.

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

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

• Junctions 44 to 46 opened in 2009
• Junctions 49 to 51 opened as of the 31 March 2012. Work began in March 2009 to upgrade the Dishforth to Leeming section to dual three-lane motorway standard with existing connections being replaced by two new junctions. This work was completed on 31 March 2012.

Scotch Corner to Gateshead

The Scotch Corner to Gateshead section is 30 miles (48 km), and opened in stages:

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