Longmen Yellow River Bridge is located at the exit of Shanxi-Shaanxi Gorge. The wind environment is complex and it is difficult to be affected by the ice age of the Yellow River. However, the smooth construction progress has made foreign supervisors admire it. Under each pier of this bridge, 44 huge bored piles are drilled into the river bed, with a depth of 90 meters. This huge bridge cap is as big as a basketball court and uses 5000 tons of cement. There are 85 such bottle caps. The bridge was designed by the Second Highway Survey and Design Institute of the Ministry of Communications and divided into two sections. After international competitive bidding, it was built by China Railway Bridge Bureau Group Corporation and supervised by Chang 'an University.
