The A1 is the road from London to York and Scotland. The earliest such route was Roman; it later became Saxon, Ermine Street later the Old North Road. Later still a variant route was the Great North Road and in the 1920s bypasses were built. The South Mimms Roundabout is Junction 1 of the A1 (M) and is where the A1 going north becomes the A1 (M) motorway and goes north-south under the roundabout at the lowest level. It was built as a three lane motorway to meet the similar Barnet bypass to the south but it has been changed to a two-lane road to improve flow because of traffic conflicts. The old third lane became a slip road for the M25 and to the service area.
This is a three-level roundabout interchange providing access between the M25, the A1 (M) and a number of other roads as well as the South Mimms services. It is Junction 1 of the A1 (M), and Junction 23 of the M25The three-level stack roundabout is one of the largest roundabouts in the UK. It is known as Bignell's Corner, after a garden centre that stood north of here on the roundabout between the A1 and the A6.
Blanche Farm. This was an estate called Blanches, belonging to John Durham in the 14th and owned by a succession of wealthy people and sold in the early 20t to the Trotters of Dyrham Park.

Welcome Break. The roundabout provides access to the motorway service area which caters for cars and coaches. In 1986 As the M25 neared completion, the north-east quadrant of the junction was designated as a service area. A motorway maintenance depot was already in place there. BP was the owner of the services and its opening in 1986. They leased out the main facilities to Trusthouse Forte who branded it as Welcome Break, a chain they had just acquired. Trusthouse Forte are not now involved
Days Inn. Days are a big chain of American hotels. They sort of describe this as their ‘London’ Hotel.
St. Albans Road
This was the major route which ran through this area as the A6 from Barnet towards St Albans and Carlisle. When the Barnet bypass was built it crossed the A6 and then it was renumbered as A1. The cross roads became a roundabout which still exists to the north east of the main motorway interchange.

Beacon Café. Truck stop. This predates the M25 and was the first service area on the M25. The original building was destroyed in 1998 following a fire in a deep fryer. The Beacon café had been built specifically to provide a stopping place for BP truckers. It included fast diesel pumps, a truck shop, rest room and a dedicated room for gaming machines. It was also infamous for its prostitutes. The truck stop has since become further integrated into the main service area. The site of the café itself is now the Scania Depot.
