What special challenges did the builders face while building the donghai bridge?

The builders of the Donghai Bridge faced several significant challenges, including harsh weather conditions, such as typhoons and strong ocean currents, which complicated construction and required advanced engineering solutions. Additionally, the deep waters and varying seabed conditions necessitated innovative foundation techniques to ensure stability and durability. Environmental concerns also posed challenges, prompting the need for careful planning to minimize ecological impact. Finally, the logistics of transporting materials and coordinating a large workforce over the vast construction site added complexity to the project.
