Top 7 of the world’s largest bridges

The architectural developments show us that what was once considered impossible may become an unquestionable achievement. When the Golden Gate opened in the thirties, people did not believe that someone could build longest bridges. The truth is that every time longer bridges are built, defying many architectural paradigms. In this post, you will find some of the longest bridges in the world and brief descriptions of their technical characteristics.

  1. Lake Pontchartrain Causeway

The Lake Pontchartrain Causeway (New Orleans, Louisiana), has a length of 38.422 km. The highway bridge crosses Pontchartrain Lake and connects Metairie, a suburb of New Orleans, with Mandeville. It begins at the South Shore at Jefferson Parish and ends at the North Shore at St. Tammany Parish.

The bridge is an erected beam bridge of pre-stressed precast concrete sections with field extensions of 17 meters on a total of 9000 concrete pillars. It consists of two separate parallel structures, 24 meters apart, one of which was completed in 1956, the other in 1969. Since then, both directions have been separated in one-way traffic. On the older bridge the traffic goes south. Each direction has two lanes.

The Jiaozhou Bay Bridge (or Qingdao Haiwan Bridge) links the city of Qingdao in Shandong Province with the Huangdao district through the waters of the northern sector of the Bay of Qingdao. Its length is 42.5 km and reduces the distance between the cities of Qingdao and Huangdao in 31 km, reducing travel time by half (approx. 40-20 minutes.)

The construction of the bridge lasted four years and employed more than 10,000 people. For its construction 450 000 tons of steel and 2.3 million cubic meters of concrete were needed. The design was provided by Shandong Gaosu Group. The bridge is designed to withstand earthquakes of high intensity, typhoons and ship collisions. The bridge is supported by over 5,000 pillars, and has a width of 35 meters, with 6 lanes and two hard shoulders. The cost of the bridge is about 14,800 billion yuan (USD 2.3 billion.) The bridge reduces the distance between the two points by half (30 km.)

The building begins about seven kilometers after the South Railway Station in Beijing, in the Fengtai district, south of the 4th Ring Road, crosses the Daxing district and ends in the Hebei province, just before the railway station. The beam bridge consists of prefabricated concrete parts, except for the Jingkai Expressway (G45 / G106), which is constructed with a curved bridge of hollow steel hollow beams. The supporting width of the arch bridge created in Free Vorbau is 108 m. It crosses the six motorway lanes and the two two-lane side streets.
