Beam erection of the first span section of the Huangmao Sea Channel project's east approach bridge was completed on April 25, marking another step forward toward the project's completion in 2024.

CCCC Second Highway Engineering is undertaking the prefabrication and assembly of segmental beams for the T9-section of the Huangmao Sea Channel project, which is divided into the two construction areas of the 4,200-m (2.6-mile) east and west approaching bridges. A total of 2,270 segments will be installed, with each of them being 3.6 m (12 ft) in height and 16.5 m (54 ft) in width.

Zhu Chao, chief engineer and deputy director of the project's management center, noted that automation and smart technologies are being applied to digitalize the whole construction process for a higher quality of segment prefabrication and assembly. 

To date, the mid and west towers of the 2,200-m (1.4-mile) Huangmao Sea Channel Bridge has finished concrete pouring on 10 of its 45 sections, with the five towers on the Huangmao Sea Channel and Gaolan Port bridges being over 25 percent finished. The tower main structures are expected to be completed in mid-2023.

Work on the approach bridges, two tunnels, and four interchanges is also underway. By now, 80 percent of the foundation for over 3,000 root piles has been completed, as well as 40 percent of the concrete pouring for the piles of the approach bridges finished.
