Introduction to the highway bridge along the Yellow River: In the past, there were neither boats nor bridges at the Yellow River crossing. People had to rely on cattle and sheepskin rafts to make the transition. In 1966 after liberation, the first reinforced concrete bridge on the upper reaches of the Yellow River, the Yellow River Highway Bridge, was built. It connects the mountains, rivers and grasslands on both sides of the Taiwan Strait, and integrates the herdsmen into the warm family of the socialist motherland.
