World's Most Amazing Bridges

Hongyagu Suspension Bridge

Hongyagu Bridge - World's longest glass bridge

Hongyagu Bridge - World's longest glass bridge
The 6.5 feet wide walkway in the Hongyagu Scenic Area in Hebei province hangs 755 feet above the ground, and is the world's longest bridge, which opened in 2017-end. Designed by Tel Aviv architect Haim Dotan, it measures 488 metres across and links two peaks in the mountainous region of north-eastern China. The most thrilling feature of the 70-ton bridge is that it has been designed to 'sway a little' to entertain visitors.

Made of 1,077 panels of 4-cm thick glass and supported by cables that weigh over 120 tons, the bridge can take the weight of 2,000 people. However, to ensure safety, the management has decided to limit the number of tourists to just 500 to 600 at any one time.The record-breaking bridge took three years to construct, and is 191 feet longer than the Zhangjiajie Grand Canyon (the world's second longest glass bridge) in China.

Hong Kong-Zhuhai-Macao Bridge: World's longest cross-sea bridge

Hong Kong Zhuhai Macao Bridge
The Hong Kong-Zhuhai-Macao bridge, and the largest steel-structure bridge, is close to completion. It took six years preparation, and eight years to build this technologically complicated 55-km long bridge that links Hong Kong, Zhuhai and Macao. Once operational, it will cut down driving time between Hong Kong and Zhuhai from three hours to only 30 minutes.

The Y-shaped bridge has boundary-crossing facilities in each of the three cities, and three link roads. The main body is a combination of bridge, tunnel and artificial islands. Its dual three lane highway is designed to withstand major earthquakes or super typhoons.

It has used 420,000 tons of steel (enough to build 60 Eiffel Towers) and consumed 1.08 million cubic meters of cement. The bridge will enhance connection of the bay area, and boost exchange of personnel, goods, information and capital between the three places. It also guarantees better transportation, development and integration of the region, and will be a social, economic, cultural, and tourism connection among the three areas.

Charles Kuonen Hängebrücke:  World's longest pedestrian suspension bridge

Charles Kuonen Hängebrücke: World's longest pedestrian suspension bridge

The Charles Kuonen Suspension Bridge (also known as the Europe Bridge) in the Swiss Alps, is a record 494-metre long. It connects Grächen and Zermatt on the Europaweg foot trail. It is located in Randa, Switzerland, and replaced the defunct Europabrücke (de), which was damaged by a rock slide. Constructed by Swissrope, it is the longest pedestrian suspension bridge in the world, and hangs 84 meters above the ground at its highest point, and is 1,600m to 2,200m above sea level.

Held up with 7.9 long tons and 8.8 short tons of cables, the bridge has a 64-cm wide metal deck, and has a system that prevents it from swinging. Of steel construction with a grated steel foot bed, it allows hikers to gaze down into the chasm below. Incredibly, it took engineers from Swissrope and Lauber cableways just 10 weeks to erect the bridge. The structure, which is just 65cm wide, takes 10 minutes to cross; a journey that previously took hikers four hours.
