Smart systems safeguard China's mega cross-sea link

As one of the most technically complex infrastructure projects in China, the Shenzhen-Zhongshan Link relies on advanced digital and intelligent systems to operate safely across the Lingdingyang waters.

The 24-kilometer corridor, which features two bridges, two artificial islands and an underwater tunnel, is supported by real-time weather monitoring, AI-driven traffic alerts, and automated emergency response tools.

To enhance its resilience against rapidly changing meteorological conditions, the Shenzhen-Zhongshan Link has recently upgraded its weather forecasting and early warning systems.

"The meteorological data of the Shenzhen-Zhongshan Link integrates different data from Shenzhen, Guangzhou and Zhongshan. And the weather at the Pearl River Estuary changes very often," said Wang Yuzhong, engineer at digital management department at the Shenzhen-Zhongshan Link Administration Center.

Weather data and road status are fed in real time to the traffic command center nearly 20 kilometers away. Over 800 high-definition surveillance cameras and drones continuously monitor traffic conditions across the bridges and tunnel. Anomaly detection systems analyze road surfaces and vehicle flow, automatically flagging irregularities. From detection to on-site dispatch, emergency response is triggered within seconds.

While bridge events are easier to assess, incidents inside the 6.8-kilometer tunnel present greater challenges. To address this, the upgraded system has established a database of emergency scenarios and more than 700 pre-configured response plans.

"If a tunnel fire occurs, personnel only need to input the incident's location and direction. The system matches the data to the emergency library and generates a tailored response plan. With one click, over 400 devices are activated in seconds," said Liu Bibo, deputy director of the digital management department at the center.

The Shenzhen-Zhongshan Link's smart operations platform integrates intelligent traffic control, real-time incident alerts, and digital coordination between multiple agencies - fire services, traffic police, road administration, and rescue units receive simultaneous alerts and can reach the site quickly.

Russian military holds strategic initiative along entire Russia-Ukraine conflict front: Putin

Russian President Vladimir Putin said on Wednesday that Russia holds the strategic initiative along the entire front lines and the goals of the country's special military operation in Ukraine will be achieved.

"The past year has been an important milestone in fulfilling the tasks of the special military operation," Putin said while addressing an expanded meeting of the Russian Defense Ministry.

Putin underscored that Russia has the capability to accelerate its offensive pace, adding that Russia's task of expanding the security buffer zone will be fulfilled, and the core goals of the operation will be realized.

"This year alone, more than 300 settlements have been liberated, including major cities that the enemy had turned into fortified strongholds equipped with long-term defensive structures," the Russian leader said.

He said that the Russian military currently holds the strategic initiative along the entire Russia-Ukraine conflict front and is defeating Ukrainian forces, including elite Ukrainian units trained in the West.

Russia is currently seeking mutually beneficial and fair cooperation with the United States and European countries, Putin said.

Putin rejected claims portraying Russia as a threat to European nations, saying that such narratives are unfounded and fabricated.

Putin also announced that several submarines and surface ships have been commissioned into the Russian Navy this year, while the "Oreshnik" missile complex will enter combat duty by the end of 2025.
