I guess it would be an interesting run into Cannon Street otherwise
What was at street level where the big concourse is now - Leon etc?
Before the rebuild it was all railway arches of various designs (built in different eras as the station has expanded). Many of them were empty or used as storage for Network Rail, but there was also a telephone exchange, wiring rooms for signalling, a large 'artsy' nightclub called Shunt (
some photos), and a gym. Not to mention Stainer Street which was a road that cut underneath the platforms, similar to Bermondsey Street.
The new platforms are all at exactly the same level as the old (within a few centimetres). Don’t forget that those old ramps took you down to a level that was still a long, long way above street level.
Yeah. the ramps still exist (with substantial modifications, some are now stairs) as part of the fire escape routes for the new platforms. They did (and still do) bring you down to the same level as the
Cottons Centre footbridge over Tooley Street. For those who remember London Bridge after the redesign, after reaching the bottom of the ramps you could go right over the footbridge, left out to the bus station (which is at a similar elevated level) or forwards down some escalators which brought you down to Joiner Street / Tooley Street. Those escalators still exist although they have been closed since before the pandemic for refurbishment - I imagine that given they receive very little footfall after the rebuild, sorting them out is not considered a priority, especially at the moment.
The route is still useful as a way from the bus station to the tube although you can also go through the Shard Arcade.
The Cottons Centre footbridge is
going to be demolished at some point soon.
