The ten longest bridges in the world are located in three countries: China, America and Thailand. Many of these bridges are rail bridges for high speed trains. The rest are for cars and trucks. China has the most at 7 and America has two. Thailand rounds out the list with only one. Each of these bridges spans a vast amount of water in order to complete either a rail system or a roadway. They range from 102 miles to just 22 miles in length.
China

China has the three longest bridges in the world. They are the Danyang-Kunshan Grand Bridge at just over 102 miles, the Tianjin Grand Bridge that is 70 miles long and the Weinan Weihe Grand Bridge topping out at 49 miles. All of these spans are railway bridges. China makes the list with four more bridges. In position number five for length is the Beijing Grand Bridge at just under 30 miles. It is a bridge for high speed rail. China finishes off the last of the top ten bridges with the final three. These are Yangcun Bridge, the Hangzhou Bay Bridge and the Runyang Bridge.
