The most incredible bridge is on the quiet Jianhe River. There is an ancient wood truss Bridge-"Math Bridge". The most famous bridge in this area has been accompanied by the oldest building along the Jianhe River-the red brick residence of the Dean of Queen's College, Cambridge University, which has gone through more than 250 years. The legend of "Mathematical Bridge" is a household name in Cambridge. According to legend, the great mathematician Newton personally designed and built the bridge when he was teaching in Cambridge. The whole bridge is not fixed with nails and screws. Later, in order to explore the mystery of the bridge, the students of Queen's College took it apart for analysis, but it could not be restored and had to be fixed again with nails. It is also said that this is the masterpiece of British bridge designer William Esridge when he was studying at Queen's College. In addition, he was inspired by Chinese bridges after traveling in the East. In fact, the bridge was built by James Essex Jr. according to Esrich's design. The prototype of modern steel beam bridge is displayed, and the included angle between adjacent trusses of the bridge body is 1 1.25 degrees. In the18th century, this design was called geometric structure, so this bridge was named "Mathematical Bridge". 2. The longest double-deck bridge, Akashi Strait Bridge in Japan, lies between Honshu and Shikoku, with a main span of1991m (960+1991+960) and a total length of 39 10 m, and is a three-span double-hinged truss girder suspension bridge.

The midpoint of the steel cable hangs down, almost close to the bridge body, and the steel cable and the bridge body are connected by thin steel cables. The whole Golden Gate Bridge looks simple and magnificent. In memory of designer and engineer Strauss, people put his bronze statue on the bridge. On the day when the Golden Gate Bridge was completed, 200,000 people happily crossed the bridge to celebrate this day. Today, the Golden Gate Bridge is one of the busiest bridges in the world, with about 654.38 million cars rumbling by every day.

At that time, there were windows on the bridge, and prisoners could take a last look at the world. When crossing the bridge, they looked at the world they were leaving.

Every year, countless couples come to this bridge to kiss, because it is said that kissing on the bridge of sighs will make love last forever. 6.
