The Greenwich and Woolwich Foot Tunnels were originally built in 1902 and 1912 respectively. The purpose of the tunnels was to provide reliable all-weather access by local residents to the London shipyards and docks on the north side of the Thames. Both foot tunnels were built by the former London County Council.
The Greenwich Foot Tunnel crosses beneath the River Thames in East London, linking Greenwich(Royal Borough of Greenwich) on the south bank with Milwall (London Borough of Tower Hamlets) on the north. Approximately 4,000 people use the tunnel (open 24/7) each day. It opened in 1902.
