North Circular Road
The North Circular Road (officially the A406 and sometimes known as simply the North Circular) is a  ring road around Central London in England. It runs from Chiswick in the west to Woolwich in the east via suburban North London. It connects lots of suburbs and other trunk roads in the region. Together with the South Circular Road, it forms a ring road around central London. This ring road does not make a full circuit of the city. Instead, it is C-shaped. This is because the crossing over the River Thames in the east is made on the Woolwich Ferry.
