189 1 year, the Qing government issued an imperial edict to build a trestle in Qingdao. 1892, the Qing government sent Gaoyuan Zhang, the governor of Dengzhou, to station four battalions of officers and men in Qingdao. In order to facilitate the transportation of military materials, two docks were built, one of which is the present trestle. There are many original names of docks, including Navy Wharf, Qianhai Wharf, Nanhai Wharf, Li Hongzhang Wharf and Grand Wharf. It is 200 meters long and 10 meters wide. Another "Yamen Bridge" is located in front of the company commander's Yamen, with a length of 100 m and a width of 6 m, also known as the "snail bridge". These two wharves were designed by China engineers themselves, and they were also the earliest wharf construction in Qingdao Port. 1897, the Germans landed from Qingdao Bay in the name of exercise and occupied Qingdao by force. This trestle became the witness of German occupation of Qingdao. After German imperialism invaded Qingdao, the northern end of the original bridge was changed into a stone foundation, covered with cement, and the southern end was erected. The steel bridge is covered with wooden boards and equipped with light rail. The southern end is still an iron-wood bridge, the bridge body is extended to 350 meters, and it is still a military pier. 1904 After the completion of Terminal 1 in Dagang, the trestle gradually lost its historical mission as a wharf and began to open to tourists.

1922, Qingdao was taken back by China. 193 1 year, the national government invested heavily in the reconstruction of the bridge by the German Xinli foreign firm, and the bridge was extended to 440 meters. A semi-circular breakwater was built at the southern end of the bridge, and a two-story octagonal pavilion with national form was also built on the breakwater. Covered with colored glazed tiles and supported by 24 red paint columns, the pavilion is named "Huilan". The whole project was completed in April 1933. Since then, the trestle bridge has become the first scene in Qingdao. After the establishment of People's Republic of China (PRC), the people's government allocated funds for the maintenance of the trestle bridge for many times. 1985 Qingdao has carried out a large-scale comprehensive transformation of the trestle bridge, with iron rope guardrails on both sides. 12 pairs of European bridge lights stand side by side, and granite steps are paved outside. 1from the end of 1998 to1June 1999, the municipal government once again allocated funds for large-scale renovation of the trestle. This maintenance not only meets the requirements of wind and waves prevention and corrosion prevention, but also maintains the original charm, and with the bank protection facilities on both sides, it increases the aesthetic effect.
