North Woolwich in the context of "North Circular Road, London"

The North Circular Road (officially the A406 and sometimes known as simply the North Circular) is a 25.7-mile-long (41.4 km) ring road around the northern half of inner London. It runs from Chiswick in the west to North Woolwich in the east via suburban north London, connecting various suburbs and other trunk roads in the region.

Together with its counterpart, the South Circular Road, it mostly forms a ring road around inner London, except for crossing of the River Thames, which is done by the Woolwich Ferry.

The Woolwich Ferry is a free vehicle and pedestrian ferry across the River Thames in East London, connecting Woolwich on the south bank with North Woolwich on the north. It is licensed and financed by London River Services, the maritime arm of Transport for London (TfL). Around two million passengers use the ferry each year.

A ferry has operated on the Thames at Woolwich since the 14th century, and commercial crossings operated intermittently until the mid-19th. The free service opened in 1889 after tolls were abolished on bridges to the west of London. Traffic increased in the 20th century because of the rise in motor vehicle traffic and it remained popular because of the lack of nearby bridges. Pedestrian use dropped after the construction of a parallel foot tunnel and the extension of the Docklands Light Railway to Woolwich Arsenal station. Alternatives such as the Thames Gateway Bridge and Gallions Reach Crossing have been proposed as replacements, but there are no plans to discontinue the Woolwich Ferry as long as there is demand.

The Woolwich foot tunnel crosses under the River Thames in Woolwich, in East London from Old Woolwich in the Royal Borough of Greenwich to North Woolwich in the London Borough of Newham. The tunnel (open 24/7) offers pedestrians and cyclists an alternative way to cross the river when the Woolwich Free Ferry service is not operating. Both entrances to the tunnel (north entrance at 51°29′56″N 0°03′42″E / 51.49879°N 0.06165°E / 51.49879; 0.06165 (Woolwich foot tunnel, north entrance) and south entrance at 51°29′40″N 0°03′46″E / 51.49432°N 0.06289°E / 51.49432; 0.06289 (Woolwich foot tunnel, south entrance)) are Grade II listed buildings. The south entrance is somewhat hidden behind the Waterfront leisure centre. It is the oldest remaining building in the riverside area of Old Woolwich.
