London is a city of bridges, connecting its two sides which are dissected by the River Thames.
But this is an exception to the rule. Some Edwardian engineers saw fit to construct a tunnel beneath the river. To this day, it carries pedestrians from Greenwich in the south to the Isle of Dogs on the north bank and is open 24/7. You can take the original staircase or a lift to reach the tunnel.
The brightly lit, white tiled tube is a photographer’s dream for capturing perspective, distance, shape and lines. It’s just busy enough to capture both figures and eerie emptiness. The only hazard is cyclists using it as a race track, despite signs prohibiting this.
Well worth the long trip from west London, where there is no underwater thoroughfare.
