Stainer Street has reopened to the public as a north-south pedestrian route from Tooley Street to St Thomas Street parallel to the concourse of the rebuilt London Bridge Station.
Until work started in 2012 on the project to rebuild London Bridge Station, Stainer Street was a fume-filled tunnel used by buses and cars heading north to Tooley Street as part of the one-way traffic system.
"As well as enhancing London's fourth busiest station for travellers, we wanted to improve the experience of living in the area for the local community and its attractiveness as a destination for visitors," said Simon Blanchflower, director of Network Rail's Thameslink Programme.
"We've done this through the conversion of Stainer Street into a walkway that is bright and welcoming. Working with leading artist Mark Titchner we've been able to create something special which we hope will encourage users to engage with their surroundings, be wowed and reflect in one of the busiest parts of London."
Network Rail has gone back on its commitment – given at the time that the station project won planning approval in 2011 – that Stainer Street would be open 24 hours a day. The walkway will close for three hours each night between 1.30am and 4.30am for security reasons and to allow servicing to take place.
Mark Titchner added: "During the frantic activity of commuting, one's thoughts tend to wander away from the 'here and now' and travel becomes the space between two destinations of the mind as well as the body.
"Although we're surrounded by others, we remain separate, quietly alone with our thoughts, dreams and anxieties and this work seeks to address that by providing a space for self-reflection with our fellow travellers giving that mental space a physical form which unites us as individuals with those around us."
