How did China manage to build the world’s widest underwater roadway in only 110 days?

China accomplished the world's widest underwater road, the Jinan Huanggang Road tunnel, under the Yellow River in 110 days, a remarkable engineering achievement.

This ambitious project demonstrates China's rapid construction timeline and sophisticated infrastructure capabilities. By the end of 2025. The tunnel will likely transform the region's connectivity.

Spanning two miles with a width of 55.8 feet, the tunnel was excavated using the colossal "Shanhe," the largest tunnel boring machine ever deployed. With a surprising efficiency, "Shanhe" dug through the riverbed at a rate of almost 59 feet each day. This technological wonder highlights the project's scope and accuracy.

The six-lane tunnel, which is supported by 500 strong pipe rings, is intended to smoothly connect the northern and southern banks of Jinan. This crucial connection will improve traffic flow and stimulate the local economy. An example of creative engineering and its capacity to transform urban environments is the Jinan Huanggang Road tunnel.
