The M25 motorway marks the western boundary of Coinbrook, Berkshire with which London village that may also be considered a hamlet?
M25 motorway The M25 or London Orbital Motorway is a 117 mi motorway that encircles almost all of Greater London, England (with the exception of North Ockendon), in the United Kingdom. An ambitious concept to build four concentric ring roads around London was first mooted in the 1960s. A few sections of the outer two rings were constructed in the early 1970s, but the plan was abandoned and the sections were later integrated to form a single ring which became the M25, aka London Ring Road, finally completed in 1986.
Coldharbour, Havering Coldharbour is an area of the London Borough of Havering by the River Thames and southwest of the Rainham Marshes Nature Reserve. It is the location of Coldharbour Point, where there has been a lighthouse since 1885. This point is adjacent to the town of Erith in Bexley, across the Thames. The nearest accessible settlement on land is the town of Rainham, which is connected by Coldharbour Lane; the village of Wennington is also nearby but not accessible by road (both are separated by the A13 and marshlands). The area around the point is mainly industrial land known as the Freightmaster Estate depot. The London Loop passes through Coldharbour on its way east to Purfleet in Thurrock.
