|Route outline (key)|
The A1 is perhaps the most significant road in the United Kingdom. Not only is it the longest, but it links the English and Scottish capitals, and is known as the Great North Road. The A1 is more than just a road, however; it is significant for having several different characteristics, from city route, to urban dual carriageway, to busy rural motorway. Indeed, the A1 is a road of many flavours.
London to Peterborough: from the heart of the capital to fields of the East Midlands
Peterborough to Newcastle: through the East Midlands and Yorkshire
Newcastle to Edinburgh: through the Borders and onwards to Edinburgh
Roader's Digest Entry
In the early days of SABRE a number of members got chatting late one night and started discussing duplicate numbers of roads. The discussion soon developed into an idea to write up all the roads in the country and, indeed, some early members got very carried away with the whole thing...
Due to the piecemeal nature of the upgrades of the A1, the system of markerposts on the route is very complicated. There are several "zero" points along the route, notably at the start in London, near Huntingdon , at Blyth Interchange (Junction 34) near Doncaster, and at Junction 56 at the start of the Durham section of motorway. More details on this can be found in an article on the Roads.org.uk website (see links at bottom of page).
Do you want to know when an A1 bypass, dual carriageway or motorway section was built? This article tables each scheme from Edinburgh to London and can be also be listed in date or location order. Includes tables for the continuous dual carriageway from Morpeth to London, early single carriageway schemes, motorway schemes and superceded sections.
Road upgrades and bypass construction has continued since the first bypass - the Ferryhill Diversion of 1923. This article gives more detail of each scheme up to 1979. These schemes, including the 1960s bypasses around market towns such as Newark, Grantham, and Stamford, have massively reduced travel times on the Great North Road and provided vital relief for traffic choked towns.
The A1(M) Bramham to Wetherby scheme was an on line upgrade of the A1 dual carriageway between junctions 44 and 46, costing £70 million. This section of the A1(M) carried 85,000 vehicles per day.
