In just 110 days, China has achieved a remarkable feat of engineering — completing the world’s widest underwater roadway, the Jinan Huanggang Road Tunnel beneath the mighty Yellow River. Measuring 55.8 feet wide and stretching over 2 miles, the tunnel was excavated with "Shanhe", the largest tunnel boring machine ever used in the region, capable of cutting through the riverbed at a rate of 59 feet per day.
What makes this project even more impressive is its structural precision: it required over 500 reinforced pipe rings to stabilize the underwater passage. Once operational in late 2025, this six-lane tunnel will serve as a vital link between the northern and southern districts of Jinan, reducing congestion, boosting logistics, and symbolizing China's commitment to next-generation infrastructure.
This isn't just a tunnel — it’s a milestone in rapid urban connectivity built at an unprecedented pace.
