pictogrammeChongming Tunnel - 2009

Chongming Tunnel - 2009As part of a vast motorway project linking the Shanghai-Pudong district to the neighbouring province of Jiangsu, Bouygues Construction built the Chongming Tunnel connecting the island of Chang Xing to the Shanghai-Pudong district on the mainland. Driven with the world's largest two tunnel-boring machines (15.43 m in diameter), the three-lane twin tubes of the 8‑km‑long tunnel will set a Chinese record for the length of tunnel under water.
