Haohe Bridge is located within the jurisdiction of Wangqu Subdistrict Office in Chang'an District. It is a major bridge spanning the Haohe River and Outer Ring Road 238 Township Road, with a length of 756 meters, 134 pile foundations, 116 pier columns, 300 box girders, and 1,500 meters of bridge deck pavement.

In terms of construction technology, we generally follow the construction principle of completing the main structure first and ancillary works afterward. Rotary drilling is used for hole formation in bridge pile foundations; the bent cap construction adopts the hoop method and factory-made integral safety protection platforms; bridge erection uses an integrated machine for full-width erection; and subgrade work is carried out by longitudinal segmentation, transverse layering, and top-down excavation. During construction, strict control is exercised over each process, and the "three inspections" system of self-inspection, mutual inspection, and handover inspection is strictly implemented.
