The A1000 is a main road in the United Kingdom, going from London to Welwyn.
The A1000 was formerly known as the Great North Road (and parts of it still bear this name),[1] or A1, but after a bypass was built in the 1920s it became the A1000. The 1922 Road Lists describes the A1000 as Finsbury Park station to Muswell Hill, which made it a quite short road. This road was later reclassified as part of the A1201.[2]
The A1000 starts at East Finchley, North London,[3] and travels for approximately 20miles to Welwyn, where it joins the A1(M) motorway.[4] On its route it passes through Chipping Barnet, Potters Bar, and Hatfield,[5] and goes through the Traditional Counties of Hertfordshire and Middlesex.[6]
