Today's Waibaidu Bridge is the third generation. A century's memory-Waibaidu Bridge

The first generation well bridge (1856 to 187 1 year) is folded.

1855, the sluice bridge built during Yongzheng period on Suzhou River collapsed, and the traffic problem became more acute. /kloc-in 0/856, Suzhou River Bridge Company (the first bridge-building company in China), founded by 20 people (mostly auspicious bank managers or opium dealers), including British Welsh who used to work for Jardine Matheson Group and Ren Wei and Homer of Baoshun Jixiang Bank, invested in the construction of the first generation Waibaidu Bridge, which was named "Wells Bridge" as a single-plank bridge.

The folding of the second generation of the second generation foreign ferry bridge

Because the original intention of the Wells Bridge was just to make a profit. Therefore, Suzhou River Bridge Construction Company is only responsible for collecting bridge tolls, ignoring the most basic bridge maintenance. So in less than six years, the wooden foundation of Wells Bridge began to rot and the deck tilted. Under the pressure of the Ministry of Industry, Suzhou Creek Bridge Construction Company had to plan the construction of the new bridge. Subsequently, Shanghai residents protested angrily, and Cantonese Zhan Ruoyu set up a post office at today's Shanxi intersection to pick up and drop off Chinese passing by on both sides of the strait for free to show his unyielding. Because citizens no longer pay money, it is called "white crossing". Due to public anger, the concession industrial and commercial office built a wooden pontoon bridge near Wells Bridge on 1876, and the bridge was free. Because it is adjacent to the Bund Park, the British called it "Garden Bridge" in those days, and a bronze monument was carved at the bridgehead (the bronze monument was destroyed after 1949), while the common people called it "Waidukou Bridge". Since then, there is no charge for crossing the bridge here, and the Wells Bridge was demolished by the Ministry of Industry. In the following decades, people made a slip of the tongue and read it as "Waibaidu Bridge". Therefore, it has always followed the convention. Today, this Waibaidu Bridge is more than just the name of a bridge.

Folding of the Third Generation Waibaidu Bridge

The existing Waibaidu Bridge was built at 1907. At the beginning of the 20th century, with the use of new means of transportation and the increase of passenger flow, the original wooden bridge was not enough, so the wooden bridge was demolished at 1906. The construction of the new bridge was put on the agenda, and the Ministry of Industry decided to build a new steel bridge to accommodate trams and cars. The construction of the new bridge is supervised by the Ministry of Industry of Shanghai Concession, and the required steel is imported from Britain. The new Park Bridge, today's Waibaidu Bridge, was designed by British businessman Howard erskine Co., Ltd. in Singapore and built by British businessman Cleveland Bridge Engineering Co., Ltd. in Darlington, Durham, England. The company built the Victoria Falls Bridge across the Zambezi River in Zimbabwe last year. The new Waibaidu Bridge was officially started on August 4th 1906 and completed on February 29th 1906 the following year. 190865438+1On October 20th, the Ministry of Industry and Information Technology held the opening ceremony of the new bridge. When it was opened to traffic, Waibaidu Bridge was the largest steel bridge in Shanghai at that time and the first steel truss beam in China. Because it is made of steel, it is called "the strongest bridge in China" by the media. The total length of the newly-built bridge is104.39m, the lane width is11.2m, and the sidewalks on both sides are 2.9m.. The clear height of the bridge is 3.25 meters at high tide and 5.57 meters at low tide, and the total weight of the bridge is about 900 tons.
