On 22 August 2026, the Young Committee of the Hong Kong Institution of Highways and Transportation (HKIHT YC), together with ICE HKA G&S, IMechE HKB and HKIE YMC, organized a technical visit to the T9 contract section of the Shiziyang Passageway Project. The visit was coordinated by the Guangdong Provincial Highway Society, with support from Guangdong Bay Area Transportation Infrastructure Investment Co., Ltd., CCCC Highway Consultants Co., Ltd. and Poly Changda Engineering Co., Ltd. HKIHT Secretary-General Ir Ken Lui joined the 45-member delegation, which comprised representatives and young engineers from the four institutions.

​

During the visit, participants attended a project briefing, viewed construction demonstration videos, and visited the smart construction exhibition hall and bridge construction site. The delegation gained first-hand insights into the design and construction of the Shiziyang Bridge, one of the key engineering elements of the approximately 35-km-long Shiziyang Passageway. With a main span of 2,180 m, the bridge is designed as a double-deck steel truss girder suspension bridge carrying a total of 16 traffic lanes.

​

The project team briefed the delegation the construction of 342-metre steel-concrete composite main tower, the use of C80 high-strength concrete, temperature and crack control for mass concrete, fabrication, erection of steel structures with stringent precision control, and intelligent structural monitoring. The project team and the delegation also exchanged views on construction planning, major construction risks, safety management of large lifting equipment and smart construction technologies.

​

The visit provided Hong Kong young engineers with valuable exposure to large-scale bridge engineering and smart construction practices in Mainland China, while further strengthening professional exchange between the engineering communities of Hong Kong and Guangdong. HKIHT will continue to provide a professional platform and facilitate technical knowledge exchange, young engineer development and the sharing of engineering experience.
