Chinese studio Architectural Design & Research Institute of Zhejiang University has completed a 526-metre-long glass-bottomed bridge in the Huangchuan Three Gorges Scenic Area of southern China.
Spanning the Lianjiang River in Guangdong Province, the structure has been officially recognised by Guinness World Records as the longest glass-bottomed bridge in the world.

Its deck is made from three layers of 4.5-centimetre-thick tempered laminated glass. It is designed to be completely clear to allow tourists to look directly down.
"The glazing endows the bridge deck with crystal-like lustre, high transparency and refractive index," said the studio.

Architectural Design & Research Institute of Zhejiang University hopes that by making the deck from glass the bridge will merge into its surroundings.
"Through blending the structure into the natural surroundings and deploying innovative construction methods, the design team realized the seamless integration of nature and the artificial."
