Thirty-five years ago today, on September 12, 1990 (July 24, 1990 lunar calendar), the second Eurasian Continental Bridge was connected between our country's Lanxin Railway and the Soviet-Turkish-Western Railway. On September 12, 1990, the western section of the Lanxin Railway and the Soviet-Turkish-Western Railway were successfully connected between Alashankou Station in Xinjiang and Druzhba Station in the Soviet Union on the Sino-Soviet border, and the second Eurasian Continental Bridge that attracted worldwide attention was announced. At 11:55 Beijing time and 6:55 Moscow time on September 12, the track laying machines of China and the Soviet Union raised huge iron arms, and at the same time slowly lifted the last rail row of each side and laid it on the wide roadbed. At 12:05, Sun Yongfu, vice-minister of the Chinese Ministry of Railways, accompanied by Timur Dawamat, chairperson of the Xinjiang Uygur Autonomous Region, and Nikki Jin, vice-minister of transportation of the Soviet Union, accompanied by Uzakbayi Karamanov, chairperson of the Council of Ministers of the Kazakh Republic, arrived at the Sino-Soviet railway rail connection and completed the final connection work on behalf of the Chinese and Soviet governments - using wrenches to tighten the bolts connecting the Sino-Soviet railway rails in turn. At 12:12 Beijing time, when the two vice-ministers simultaneously tightened the last bolt on each side of the Chinese and Soviet sides and happily exchanged wrenches, the audience broke into a long and enthusiastic applause. So far, on the Eurasian continent, a new connection between the Pacific Ocean and the Atlantic Ocean spans two continents, starting from Lianyungang in our country in the east and Rotterdam in the Netherlands in the west. The Asia-Europe Continental Bridge with a total length of 10,800 kilometers is declared to be connected. Attachment: The world's four major "land bridges" The "land bridge" is a transportation artery connecting the sea transportation on the east and west sides of the continent with an international railway trunk line on the land. Its main function is to facilitate sea and land transportation and shorten the transportation mileage. Asia-Europe Continental Bridge: This "bridge" starts from Lianyungang City in Jiangsu Province in the east and ends in Rotterdam in the Netherlands in Europe in the west. It crosses China, the former Soviet Union, Poland, Germany and the Netherlands and other countries. It spans Asia and Europe, with a total length of 10,800 kilometers. It was fully connected on September 12, 1990. It is the "youngest" land bridge in the world. North American Land Bridge: This is the earliest land bridge in the world. After the American Revolution, in order to accelerate the development of the western region's economy, the railway line was continuously extended to the west. Year after year, it has developed into today's scale. This large railway, from New York in the east to San Francisco in the west, has a total length of 4,500 kilometers. It is connected to the Atlantic Ocean in the east and the Pacific Ocean in the west, shortening the distance between the two major water bodies and saving the trouble of detouring the Panama Canal by water. South Asia Land Bridge: On the Indian Peninsula in southern Asia, there is a large east-west railway about 2,000 kilometers long from the port of Calcutta on the east coast to the port of Mumbai on the west coast. This is commonly referred to as the "South Asia Land Bridge". It allows sea transportation between the Arabian Sea and the Bay of Bengal to be converted to rail intermodal transportation. South American Land Bridge: More than 1,000 kilometers long. From Buenos Aires in Argentina in the east to Santiago, the capital of Chile in the west, it connects the two major waters of the Atlantic Ocean and the Pacific Ocean. It is conducive to cooperation between South American countries and promotes economic development.
