China's Bridge Boom
Of the world’s 10 longest bridges, 8 are Chinese high-speed rail viaducts. Most cross flat plains where viaducts are cheaper than embankments — they bypass land acquisition.
The Danyang-Kunshan Grand Bridge (Jiangsu, 2010) opened with the Beijing-Shanghai high-speed rail. At 164.8 km it set a world record that may never be broken because few projects need such length.
Iconic visual bridges (Golden Gate, Brooklyn, Akashi Kaikyō) are short by comparison. They prioritize main span (longest unsupported section) — Akashi Kaikyō has a 1,991m main span, the longest suspension span ever.
