Spanning rivers and valleys worldwide — test your knowledge of iconic bridges
The Danyang-Kunshan Grand Bridge in China holds the record as the world's longest bridge at 164.8 kilometers, while the Millau Viaduct in France rises 343 meters — taller than the Eiffel Tower. Bridges come in suspension, cable-stayed, cantilever, arch, beam, and truss forms, each engineered for specific spans, loads, and terrain.
Each round presents 10 randomized questions from a pool of 50, with four multiple-choice options and instant feedback after every answer. Your final score comes with a performance tier and shareable results.
You'll explore the Golden Gate's International Orange towers, the Akashi Kaikyo's record suspension span in Japan, the iconic Brooklyn Bridge and London's Tower Bridge, modern cable-stayed wonders like the Russky Bridge, and ancient Roman engineering feats like the Pont du Gard aqueduct. Expect questions on builders, materials, records, and memorable disasters.
The Danyang-Kunshan Grand Bridge in China stretches 164.8 kilometers (102.4 miles), carrying the Beijing-Shanghai high-speed rail line. Completed in 2010, it has held the Guinness record for the world's longest bridge of any kind ever since.
Chief engineer Joseph Strauss and his team designed the bridge with flexible, aerodynamic towers and a deck that can sway up to 8.4 meters sideways in high winds. The International Orange paint color was chosen specifically for visibility in San Francisco Bay's frequent fog.
Opened in 2004 and designed by architect Norman Foster with engineer Michel Virlogeux, the Millau Viaduct's tallest mast reaches 343 meters — surpassing the Eiffel Tower. Its seven slender concrete piers carry a cable-stayed deck across the Tarn valley in southern France.
