October 23, 2019

Bridges are incredible feats of architecture and engineering, and many have also played host to some of the world’s most pivotal historical events. Here are, five fascinating numerical facts behind some of the planet’s most interesting bridges.

Harbour Bridge

Sydney, Australia

6 million: Number of hand-driven rivets that hold the bridge together, the largest of which weighs a whopping eight pounds. The rivets were heated to red-hot and then individually driven into the bridge’s plates, and the last rivet was installed in 1932, the same year that the bridge was officially opened.

Keshwa Chaca


56: Estimated number of people who can cross the Keshwa Chaca, the last remaining Inca grass bridge in Peru, at one time. The bridge, which is suspended 60 feet above the Apurimac River in the Peruvian Andes, has been in the same location for an estimated 500 years, but because it is constructed from woven grass, it must be rebuilt every year.
