During the construction of Laheq Crossing Bridge at Red Sea Project in Saudi Arabia, CHEC not only completed the construction tasks with high efficiency and quality but also minimized the ecological impact on the Red Sea through green construction plans and innovative technologies.

The project serves as a vital transportation artery for the Red Sea tourism development, encompassing the construction of multiple cross-sea bridges and supporting road infrastructure. Once completed, the project will further enhance the transportation network of Laheq Island and its surrounding areas. This will provide robust support for coastal development along the Red Sea and actively facilitate the implementation of Saudi Arabia's Vision 2030 and regional economic growth.

The critical 2.17-kilometer section of the mainline bridge required crossing a mangrove area of approximately 30,000 square meters. Traditional construction methods would inevitably cause disturbances to the surface and local ecology. To address this challenge, the project team innovated a construction approach shifting from water-based to aerial operations. They developed the integrated piling and girder-erecting machines, "Red Sea Yuan Jing 1" and "Red Sea Yuan Jing 2," enabling the entire operational process to be conducted mid-air without touching the ground. This approach successfully left complete growth space for the mangroves.

Furthermore, the project team implemented environmental protection measures, such as preserving coral reef clusters and establishing seabird sanctuaries, taking concrete actions to minimize ecological impact and drive sustainable development.
