Abstract: The complex terrain, variable geology, and fragile ecology in mountainous areas pose numerous challenges for the construction of highway bridge clusters. The technical level of construction directly affects the quality of the transportation network and the efficiency of regional development. This study focuses on the key construction technologies for highway bridge clusters in mountainous areas, systematically analyzing the core significance and practical objectives of such research while proposing targeted technical strategies. The research indicates that these technologies not only serve as the core support for efficiently building transportation networks in mountainous regions but are also crucial for ensuring construction safety in complex environments, promoting technological innovation and upgrading, and enabling coordinated regional economic development. The primary objectives are to overcome terrain limitations, improve project quality, achieve dual control over schedule and cost, and reduce ecological impact. Based on this, this paper constructs a technical system for the construction of bridge clusters in mountainous areas from four dimensions: optimization of foundational construction techniques, application of intelligent monitoring technologies, formulation of specialized disaster prevention and risk mitigation measures, and establishment of a green construction system. It provides technical references for addressing the challenges of bridge construction in mountainous areas, enhancing the comprehensive benefits of projects, and supporting the coordinated development of transportation construction and ecological conservation in mountainous regions.
