The Greenwich Foot Tunnel crosses beneath The River Thames in East London, linking Greenwich (Royal Borough of Greenwich) in the south with the Isle of Dogs (London Borough of Tower Hamlets) to the north. The tunnel is currently open while refurbishment works continue on the entrance shafts and domes. The works were due to be complete by June 2011, but are now expected to be completed in 2014. The 'Friends of Greenwich and Woolwich foot tunnels' (FOGWOFT) was established in September 2013.
The tunnel is a convenient link between Greenwich town centre on the southern side - the entrance is close to the restored clipper Cutty Sark - and parts of Docklands including Canary Wharf. The northern entrance to the tunnel is at Island Gardens, a park on the southern tip of the Isle of Dogs, with excellent views across the river to the former Greenwich Hospital, the Queen's House and the Royal Greenwich Observatory. Because of its depth and location, the tunnel remains cool even on hot days.
The tunnel is classed as a public highway and therefore by law is kept open 24 hours a day. The tunnels are accessible by spiral staircases and large lifts (refurbished in the 2010-2012 renovations). The tunnel is also part of the UK's National Cycle Route 1 linking Inverness and Dover. Cyclists are required to dismount and push their bikes through the tunnel itself. The National Trail Thames Path also uses the tunnel to rejoin the southbound part of the path.
