The constantly bombed Yunnan-Myanmar Highway and the indestructible Gongguo Bridge are the material lifelines of the campaign in western Yunnan.

192 1 year, a horse suspension bridge "Qingyun Bridge" appeared at the intersection of Lancang River and Minjiang River. It is the first suspension bridge on the Lancang River, and Qingyun Bridge has experienced more than 90 years of vicissitudes. Gongguo Bridge, built 8 meters above 1937 Qingyun Bridge, became the throat of Myanmar highway and the lifeline of first-line material supply during its stay in War of Resistance against Japanese Aggression, so it is famous at home and abroad. It bears the historical memory of the interaction between people of all ethnic groups in western Yunnan and the historical memory of the Chinese nation's resistance to foreign aggression.

The Yunnan-Myanmar Highway was the most important international highway during the War of Resistance against Japanese Aggression period, a major channel for international aid to China, a lifeline for maintaining the whole of War of Resistance against Japanese Aggression, and the most important strategic channel for ensuring War of Resistance against Japanese Aggression's overall victory. Since the outbreak of the Sino-Japanese War of 1894-1895 and the Battle of Wuhan, China and Japan have entered the stage of stalemate. The war between the two countries has turned into a war of attrition. For China, the problem of material supply is extremely serious, and China urgently needs safe international transportation channels. Shortly after the start of War of Resistance against Japanese Aggression, the Nanjing National Government retreated to the southwest, and the coastal ports were occupied by Japan. Only the Yunnan-Vietnam Railway is still open.

After the Japanese occupation of Vietnam, China's external traffic was almost completely interrupted, and the construction of the Yunnan-Myanmar Highway became the lifeblood of the war. The construction of Yunnan-Yunnan highway needs to cross the natural barrier of Lancang River. 1937165438+10.2, the Yunnan provincial government issued an order to establish 28 counties and administrative offices in western Yunnan, recruit more than 200,000 migrant workers from all ethnic groups, build Myanmar highways and build traffic suspension bridges on the Lancang River, which brought convenience and speed to the construction.

The bridge site is 8 meters above Qingyun Bridge, which serves as a revetment. Gongguo Bridge and Qingyun Bridge go hand in hand, one is open to traffic and the other is for people. The bridge is a flexible cable suspension bridge, which started on March 1938 and was completed on May 26th. It was officially opened to traffic on June 9 and named "Gongguo Bridge".

Gongguo Bridge is the first highway bridge on Lancang River in Yunnan Province. The flexible cable suspension bridge composed of stone bridge towers has a span of 90 meters and a width of 3 meters. It can be used by 7.5-ton trucks. The opening of Gongguo Bridge has effectively alleviated the combat effectiveness of Yunnan-Myanmar Highway. However, the bearing capacity of Laogongguo Bridge is still small and its traffic capacity is low, so it is difficult to adapt to the transportation of anti-Japanese war materials soon after its completion. At the same time, Japanese planes bombed more frequently, and the Gongguo Bridge was in danger, so it was urgent to build a spare bridge. 1940165438+10 In October, a highway suspension bridge was quietly built several hundred meters upstream of the Minjiang River entrance. This is Chang 'an Bridge, which is called "New Success Bridge" by local people.

The Yunnan-Myanmar Highway was originally built urgently to transport strategic materials purchased by the China government to foreign countries and provide international assistance. With the invasion and occupation of Vietnam by Japan. The Yunnan-Vietnam railway was interrupted. Shortly after the completion of the Yunnan-Myanmar Highway, it became the only transportation channel between China and the outside world. In the early days of the Anti-Japanese War, millions of troops needed weapons and equipment; All kinds of materials needed to maintain economic operation; Countless people who moved to the rear area needed basic consumer goods, and all of them were transported to the rear area by this lifeline.

Gongguo Bridge is called the throat of Yunnan-Myanmar Highway, and its strategic position is very important. During the War of Resistance against Japanese Aggression period, the Gongguo Bridge was completed, the Yunnan-Myanmar Highway was opened, and anti-Japanese war materials were continuously transported into China, which was regarded as a thorn in the side of the Japanese invaders. In order to cut off the lifeline of China's Anti-Japanese War, the Japanese invaders set up the "Burma Road Blockade Committee" in Hanoi, Vietnam, and mobilized more than 100 planes to bomb the main bridges of the Burma Road. From 1940 and 10 to 194 12, the Japanese army dispatched more than 400 planes, focusing on bombing the two main bridges, Gongguo Bridge on the Lancang River and Huitong Bridge on the Nujiang River. Among them, Gongguo Bridge was bombed 16 times and Huitong Bridge was bombed 6 times.

Because of the dangerous terrain, both bridges are hidden on the Lancang River. Although the Japanese bombed many times, the hit rate was not high. However,1October 28th, 1940,19416, Huitong Bridge and Gongguo Bridge were successively bombed. Engineering and technical personnel and the vast number of migrant workers, regardless of life and death, Qi Xin worked hard together and joined hands with fellow practitioners in the explosion. Although the two bridges were bombed more than 20 times, the Gongguo Bridge was repeatedly damaged and repaired in the Japanese air strikes, and the Yunnan-Myanmar Highway remained unblocked. This road is called "Bombing the Burma Road".

Nowadays, because of the construction and safety of Gongguoqiao Power Station, the old Gongguoqiao has been demolished and become a site, and the Gongguoqiao, which has experienced nearly a hundred years of vicissitudes, has been replaced by the new Gongguoqiao. A brand-new Gongguo Bridge has been rebuilt, with a total length of 243 meters and a deck width of 14.25 meters, flying over the vast Lancang River, which will continue people's deep memory of Gongguo Bridge.
