LONDON‘s Tower Bridge has unveiled a new glass-bottom walkway that gives visitors a sky-high perspective of the city’s iconic double-decker red buses, pedestrians and boats from right under their feet.

Measuring 11 meters long and nearly 2 meters wide, the glass floor stretches across the West Walkway, 42 meters above the Thames River.

Each glass panel weighs 530 kg. The walkway also offers panoramic views of the city for those who may suffer from vertigo.

A second glass bottom floor is also slated to open in the East Walkway on December 1.

The newest addition to the Tower Bridge follows in the heels of other international landmarks and sites including the Eiffel Tower, the CN Tower in Toronto and the Grand Canyon, which already offer glass-bottom views.
