Potters Bar is a town in Hertfordshire, England, 13 miles (21 km) north of central London. In 2011, it had a population of 21,882. In the 2021 census, the four wards that make up Potters Bar - Bentley Heath & The Royds, Furzefield, Oakmere and Parkfield - had a combined population of 22,536; this includes several smaller outlying hamlets contained in the Bentley Heath & The Royds ward, such as Bentley Heath and Ganwick Corner. In 2022, the population was around 23,325.

Within the historic county of Middlesex until 1965, the town dates to the early 13th century but remained a small, mainly agricultural, settlement until the arrival of the Great Northern Railway in 1850. It is now part of the London commuter belt.

Thurrock (/ˈθʌrək/) is a unitary authority area with borough status in the ceremonial county of Essex, England. It lies on the north bank of the River Thames immediately east of London and has over 18 miles (29 km) of riverfront including the Port of Tilbury, the principal port for London. Thurrock is within the London commuter belt and is an area of regeneration within the Thames Gateway redevelopment zone. The borough includes the northern ends of the Dartford Crossing.

The local authority is Thurrock Council, based in Grays. The borough also includes Purfleet-on-Thames, South Ockendon, Stanford-le-Hope and Tilbury, as well as other villages and surrounding areas. More than half of the borough is designated as Green Belt.

The M3 is a motorway in England, from Sunbury-on-Thames, Surrey, to Eastleigh, Hampshire; a distance of approximately 59 miles (95 km). The route includes the Aldershot Urban Area, Basingstoke, Winchester, and Southampton.

It was constructed as a dual three-lane motorway except for its two-lane section between junction 8 (A303) and junction 9. The motorway was opened in phases, ranging from Lightwater/Bagshot to Popham in 1971 to Winchester to Otterbourne Hill in 1995. The latter stages attracted opposition from environmental campaigns across Britain due to its large cutting through wooded Twyford Down; numerous road protests were held which delayed its opening. Similar protests were avoided on the near-parallel A3 by the construction of the Hindhead Tunnel. Since completion, the motorway has been an artery to the west and midsections of the South Coast and Isle of Wight including for tourism. The major settlements nearest to the motorway are served by a railway also used for commuting but are relatively dispersed. Traffic on the M3 sees delays and congestion on its busiest sections near commuting hotspots and during holiday periods. From Chertsey to Fleet the road was in 2017 converted to a Smart Motorway, turning the hard shoulder into a permanent fourth lane with emergency refuge lay-bys.
