At the junction of Qilu and North China Plain, a steel dragon bearing the hope of regional development is quietly taking shape. On December 23, 2025, the final box girder of the Haixing Extra Large Bridge, constructed by China Construction Eighth Engineering Division, was accurately positioned. This 30 kilometer long bridge spanning rivers, highways, and villages completed the final ring of its main structure. The builders built a magnificent arc connecting the future on the vast plain with 7526 pile foundations and 890 box girders.

Five steps to overcome technical challenges

To ensure the smooth completion of the long bridge, the project team has developed a rigorous five step construction plan. The first step is precise measurement. The measurement team will find out the geographical features of the entire line in 7 days and complete the re measurement task in 15 days; The second step is to quickly enter the site, and within 45 days, more than 30 kilometers of temporary access roads will be opened, innovatively using the "surface soil storage and backfilling" technology to protect the ecological environment of farmland; The third step is to promote collaboration and achieve seamless connection between pile foundation construction and beam yard production; The fourth step is intelligent transportation, using professional beam transport vehicles to safely transport at a speed of 5 kilometers per hour; The fifth step is millimeter level lifting, which involves coordinating the lifting machine, beam transport vehicle, and bridge erecting machine to control the error within ± 2 millimeters. This systematic approach not only ensures project progress, but also creates a new standard for large-scale bridge construction.

Smart construction leads the industry

The project has achieved technological innovation breakthroughs in multiple fields. The introduction of intelligent management system in the construction of the beam yard has achieved digital control of the entire process of box girder production; Innovative application of integrated installation construction technology, synchronizing the "three walls" of the bridge deck with the box girder for factory production, significantly improving construction efficiency; We have developed specialized transportation equipment and lifting systems to solve the technical challenge of transporting up to 17 kilometers. Of particular note is that the project team has established a complete digital twin model through BIM technology, achieving visual control of the entire process from design to construction, providing a replicable technical template for similar engineering construction.

Weaving a dense transportation network pattern

As an important component of the national "Eight Verticals and Eight Horizontals" high-speed railway network, the construction of the Jinwei high-speed railway has profound strategic significance. The completion of the Haixing Grand Bridge marks a crucial progress in this fast track connecting the Beijing Tianjin Hebei region with the Shandong Peninsula. After the completion of the project, the time and space distance from the Beijing Tianjin Hebei urban agglomeration to the Shandong Peninsula will be significantly shortened, effectively promoting the development of regional economic integration. It is worth mentioning that the bridge spans three rivers, one highway, and two national highways, passing through five towns and more than 40 natural villages. During the construction process, the principle of ecological priority was always adhered to, and through scientific planning and fine construction, the impact on the local environment and residents' lives was minimized to the greatest extent possible, reflecting the harmonious unity of modern engineering construction and environmental protection.

With the comprehensive implementation of the bridge deck track laying work, this steel artery is accelerating towards the goal of opening to traffic by 2027. From the initial measurement and positioning to the current soaring dragon, the builders of China Construction Eighth Engineering Division are writing a new chapter in China's infrastructure with wisdom and sweat on the earth. When trains pass by at lightning speed, people not only feel the convenience of transportation, but also appreciate the profound impact of infrastructure construction on regional development. This fast track connecting the two major economic zones will undoubtedly become an important engine for promoting high-quality development in the northern region.
