On the 2nd, concrete pouring was completed for the ultra-deep foundation pit of the working shaft on the Wuchang section of the river-crossing tunnel in Bid Section 8 of Wuhan Metro Line 7. The foundation pit reaches a construction depth of 44.1 meters, making it the largest in cross-section and deepest in excavation among comparable projects in China, marking phased progress in the concrete construction of the main structure for this section.

Phase I of Metro Line 7 has a total length of 30.85 kilometers and 19 stations. It is an important passenger transport corridor linking Hankou and Wuchang and a river-crossing tunnel in the main urban area. The line's river-crossing tunnel is the first combined road-rail tunnel across the Yangtze River and currently the largest-diameter underwater tunnel in China.
