China on Sunday started to build its largest underwater tunnel to cross the Yellow River in Jinan, capital of east China's Shandong Province, which will facilitate the city's connectivity between parts on both sides of the river.
As one of the major channels connecting the north and south sides of the Yellow River, the tunnel is about 5,755 meters long, with about 3,290-meter section of the tunnel having to be excavated by a tunneling shield with a diameter of 17.5 meters.
"The length of the tunneling shield is equivalent to 16 buses connected end to end. The weight of the machine is comparable to that of 520 adult elephants, making it the largest among tunneling machines used in projects worldwide," said Huang Lu, person in charge of the tunneling shield of the tunnel project under China Railway 14th Bureau Group Co., Ltd.
The tunnel comprises two levels, with three lanes in each level leading in different directions, and a speed of 60 kilometers per hour. As the first single-tube double-deck tunnel cross the Yellow River, it saves urban underground space.
"The tunnel is expected to be completed in 16 months. The project will meet the requirements for the passage of buses, fire engines, maintenance and rescue vehicles," said Zhou Xiang, person in charge of the project of China Railway 14th Bureau Group Co., Ltd.
Upon its completion, it will boost the connectivity between the main urban area of Jinan on both sides of the Yellow River, and provide strong support for ecological conservation and high-quality development in the Yellow River Basin.

Ren Juncheng, captain of a large container vessel, expressed pride as a Chinese in successfully completing an evacuation mission for Chinese citizens from Lebanon amid growing tension in the Middle East.
Under the arrangement of the Chinese government, 69 Chinese citizens and 11 foreign family members in Lebanon were successfully evacuated on October 1 aboard the "Xin Xia Men" container vessel of China COSCO Shipping Corporation navigating the route from the Mediterranean to Northwest Europe.
Escalating conflicts between Israel and Hezbollah resulted in Israeli airstrikes across multiple areas in Lebanon. Given the heightened tensions in the country, the Chinese government prioritized the safety of its citizens and promptly activated the evacuation mechanism.
Due to severe disruptions in flights, the first batch of Chinese citizens needed to be evacuated by ship. The "Xin Xia Men" was the Chinese ship capable of reaching Lebanon in the shortest time, thus undertaking the evacuation mission.
Upon receiving the order at 2:00 (Beijing Time) on Sept. 29, the "Xin Xia Men" sailed overnight from Iskenderun port in Türkiye to Lebanon.
"The mission was extremely urgent, demanding immediate action upon reception. Typically, we allocate three to five days for preparation when launching a new route. However, this mission afforded us no preparation time, so we had to start the relevant work right away," he said.
As the captain of a container vessel embarking on an evacuation mission to a volatile region, Ren's primary concern was assessing the risks involved.
"As this was a cargo ship, and it was carrying over 3,000 containers at that time, my biggest concern was the potential risk of fire in case of an attack. Therefore, my immediate order was to have the crew conduct an overnight inspection of all firefighting equipment, connect all water guns and fire hoses, and have everything prepared and ready for immediate use," Ren said.
Meanwhile, all preparations for receiving Chinese citizens were also underway, including clearing rooms, preparing food and water, setting up welcome banners, and arranging safety measures. The entire crew stayed up all night.
After nearly 12 hours of full-speed sailing, the "Xin Xia Men" arrived off the coast of Lebanon at 9:00 local time on Sept. 30 and entered the country's territorial waters following permission from the naval vessel.
However, upon entering the territorial waters, the Lebanese Naval Force suddenly demanded that the "Xin Xia Men" leave Lebanon's territorial waters. Ren complied with the Lebanese navy's request to depart while simultaneously reporting the situation to the support team for further coordination.
"After that, I reflected that throughout the evacuation mission, our ship, the 'Xin Xia Men,' merely carried out specific tasks, which, in the grand scheme of things, I considered relatively straightforward. The truly challenging and intricate tasks were accomplished by the support team working behind the scenes," he said.
After coordination efforts, the "Xin Xia Men" smoothly docked at the container terminal of Beirut Port in Lebanon at 17:30 local time on Sept. 30.
Four and a half hours later, escorted by personnel from the Chinese Embassy in Lebanon, 80 Chinese citizens and their family members arrived at the terminal and began boarding the ship.
"To welcome our compatriots and their families home, our crew prepared a banner that was hung on the gangway, reading 'Welcome Home to the Motherland.' We also hung the national flag at the gangway entrance. When the compatriots and their families got off the bus and saw this banner, they were deeply moved. Some were shedding tears, while many immediately took out their phones to contact their family members back home. I heard them saying, 'Don't worry, we are safe now. The motherland has sent a ship to pick us up,'" Ren said.
At 22:30 local time on Sept. 30, 80 compatriots and their family members boarded the "Xin Xia Men" for evacuation. Departing from Beirut port at 23:48, the ship sailed to Limassol port in Cyprus. It arrived at Limassol around 8:00 on Oct. 1 after over eight hours.
"Having been a captain for over a decade, I have witnessed sunrises and sunsets in various ports around the world. While witnessing our compatriots willingly wrapping themselves in the national flag is an indescribable moment. It evokes an unparalleled closeness to our motherland. Through this evacuation mission, we truly feel proud to be Chinese and understand the pride that comes with having a strong motherland behind us," Ren said.
At 11:00 local time on Oct. 1, the "Xin Xia Men" docked at Limassol port's container terminal. An hour later, the 80 compatriots and their family members disembarked in an orderly manner, marking the end of a nearly 40-hour evacuation operation across three countries.
