The application of bridge prefabrication and assembly technology in highway construction boasts advantages such as a short construction period, controllable quality, and minimal impact on traffic. However, during its promotion, it still faces difficulties including restricted transportation conditions, challenges in controlling on-site installation accuracy, insufficient durability of component connections, and complex construction organization and coordination. Aimed at improving the quality and efficiency of highway bridge construction, this paper conducts an in-depth analysis of the main problems encountered in the practical application of prefabrication and assembly technology, explores the causes of its technical and management bottlenecks, and proposes targeted improvement countermeasures. These include optimizing the configuration of transportation and hoisting equipment, introducing high-precision measurement and control technology, improving the design of connection structures, and perfecting the construction organization and quality management mechanisms. By combining technological innovation with management optimization, the overall construction level of prefabricated and assembled bridges can be effectively enhanced, providing reliable support for the sustainable development of highway construction.
