geographical position
Dongying Shengli Yellow River Highway Bridge is located 40 kilometers at the mouth of the Yellow River, with Kenli County in Dongying City on the south bank and Chen Zhuang Town in Lijin County in Dongying City on the north bank.
bridgework
The bridge consists of three parts: the north bank approach bridge project, the main bridge project and the south bank approach bridge project. The main bridge has five holes and is 682m long, of which the main span is 288m, the side span is 136.5m and the auxiliary span is 60.5m m. The main span is the longest bridge in China at that time and the most advanced steel box cable-stayed bridge type. The approach bridge is 2 135.46m long and is a prestressed concrete box girder with a span of 30 m, with 24 holes on the south bank and 47 holes on the north bank. The bridge deck can pass four cars with a load of 55t in parallel. The width of the sidewalks on both sides is 1.5m, and the width of the outer edge of the bridge railing is 0.25m The height of the bridge is designed according to the fourth-class waterway, and the clearance is not less than 7m above the navigable water level, taking into account the characteristics of the Yellow River silting year by year. The bridge was designed according to the flood control flow of 1 1000m3/s, which was the newly-built highway bridge with the largest span, the widest deck and the largest bearing capacity in China at that time, and it was also the first steel box cable-stayed bridge built in China.
