Bridges can be built in river valleys or on both sides of the Taiwan Strait, or they can rise from the ground and cross the rivers or roads below, so that the traffic below can be unimpeded. The "bridge" was originally a tall tree (see arbor). Because it is high enough and long enough, it can be cut down and put on the river, and it can connect the two banks, so it is a single-plank bridge.

The famous bridge in China.
1. Lugou Bridge
Lugou Bridge, also known as Lugou Bridge, is located about15km southwest of Beijing, on the Yongding River in Fengtai District. Named after crossing Lugou River (Yongding River), it is the oldest existing stone arch bridge in Beijing.
Lugou Bridge is an eleven-hole composite arch bridge. The arch hole gradually increases from both banks to the center of the bridge. The arch span ranges from12.35m to13.42m.. The center of the bridge protrudes slightly by 93.5 cm, and the slope is gentle. The river bridge is 213.15m long, with a total length of 266.5m, with approach bridges at both ends. The total width of this bridge is 9.3 meters. The bridge deck is 7.5 meters wide. The bridge deck with wild goose wings on both sides of the bridge is bell-shaped and the entrance is 32 meters wide.
Stone fences are set on both sides of the bridge deck, with 140 column in the south and 14 1 column in the north. The spacing between columns is about 1.8m to 2m, and the height of columns is1.4m. The height of stone-embedded fence boards between columns is about 0.85m.. The whole bridge is a stone structure, and the key parts are connected by silver ingots and iron tenons. It is the longest ancient stone bridge in northern China.
In The Travels of Marco Polo, it was described as a magnificent stone bridge, and later foreigners called it "Kelpolo Bridge". 1on July 7, 937, Japanese imperialism launched a full-scale war of aggression against China here. The defenders of China, the ancient city of Wanping, rose up to resist, which was called "Lugouqiao Incident" (also known as "July 7th Incident"). ? China's anti-Japanese troops fired the first shot of the all-round war of resistance at Lugouqiao.
Second, Zhao Zhouqiao.
Zhao Zhouqiao, also known as Anji Bridge, is located on the Weihe River in Zhao County, Hebei Province, across a river more than 37 meters wide. Because the bridge body is all made of stone, it is called "Dashiqiao" locally. It was built in the 11th to 19th year of Emperor Yangdi's reign (AD 59 1-599), designed and built by the famous craftsman Li Chun, and has a history of 1400 years.
It is the earliest and most intact ancient single-hole open-shouldered stone arch bridge in the world today. Zhao Zhouqiao is the crystallization of ancient working people's wisdom, which has created a brand-new situation of bridge construction in China. 20 15 was awarded as one of the top ten cities in Shijiazhuang.
It is the first stone arch bridge in China. In the long years, despite numerous floods, wind and rain, snow erosion and eight earthquakes, it stood on the Weihe River unscathed.
