WORLD'S LONGEST CROSS-SEA BRIDG

---

The construction of the world’s longest cross-sea bridge, the Hangzhou Bay Bridge, which is located in China, will be completed sometime next year. If everything goes according to plan, it will be opened to traffic in June 2008. This bridge will shorten the travel distance between Ningbo in Zhejiang province and Shanghai by more than 120 km, expediting economic integration of the Yangtze River Delta. It will connect Haiyan in the northern part of Zhejiang province with Cixi in Ningbo in the southern part of Zhejiang province, promoting the development of Ningbo by providing convenient transportation.

The bridge spans 36 km of which 32 km lies above the sea, has a width of 33 meters which will accommodate 6 lanes in both directions and will have a speed limit of 100 km/h. Constructed from more than 2.4 million cubic meter of concrete, it will be supported by 7,500 concrete pilings. This bridge which cost US $1.42 billion is expected to last up to 100 years.

The huge but compact landmass of Africa can be abridged at two points, namely the Straight of Gibraltar and the Straight of Bab al Mendab, with Europe and Asia respectively. The distance between Morocco and Spain is only 9 miles and that of Yemen and Djibouti is about 12 miles. Although Africa is already connected with the Arabian Peninsula via the Sinai, there is no modern infrastructure that really joins the two continents. Now an ambitious plan to connect Yemen and Djibouti by the longest suspension bridge in the world will be undertaken by the Noor City Development Corporation of Napa, California. The American company was authorized by a Dubai-based developer, and once the bridge is completed it will have a tremendous impact on the development of Djibouti and Ethiopia as well as the rest of the Horn of Africa.
