The present A1 in London

The present A1 runs along the following roads, from South to North:

where it joins the original A1.

Here it originally continued North up the Great North Road (now A1000), but the present A1 runs West, along

and onto the North Circular Road.

After a short distance it forks right onto the Great North Way NW4 to Hendon. There is an overpass onto the M1 and it continues as the Barnet By-Pass

and into Hertfordshire. Barnet By-pass continues to the point where it crosses the M25, where it becomes the A1(M).
