On December 26,At the construction site of the Xianglin Road Viaduct in Longmatan District of the Longtouguan Tuojiang Bridge, two heavy cranes weighing 650 tons and 700 tons respectively worked in coordination, steadily and precisely hoisting the precast bent caps onto the tops of the pier columns, while workers on site quickly carried out the fixing work.

     After the first batch of 8 bent caps is hoisted, the remaining 8 are expected to be fully completed after the Spring Festival, at which point a complete pier support system will be formed, laying a solid foundation for subsequent bridge deck construction. As an important river-crossing channel connecting Jiangyang District and Longmatan District, the bridge adopts the advanced technique of "factory prefabrication and integral assembly." The 592-meter-long viaduct is designed as a dual four-lane roadway. At present, the pile foundations have been fully completed, and the installation rate of precast pier columns on the north connecting line has reached 100%. After the Spring Festival, the hoisting of precast box girders and the construction of bridge deck ancillary structures will officially begin.

     By the banks of the Yangtze River,the Yangtze River Fifth Bridgeconstruction site is likewise bustling with activity. The 192-meter-high south bank anchor tower stands towering, and workers are hurrying to hoist the final section of the crossbeam, sprinting toward the milestone of capping the anchor tower.

     The anchor towers on both banks have all reached their design heights—192 meters on the south bank and 174 meters on the north bank. After the Spring Festival, the installation of cable equipment will officially begin. Thissteel box arch bridgewith a clear span of 570 meters innovatively adopts the "arch first, girder later" construction method. At present, 50% of the main bridge foundation has been completed, and the concrete pouring for the arch abutment foundation pits is expected to be completed before the Spring Festival in 2026. Intelligent temperature control technology is used during construction to ensure that winter construction quality meets standards.

     At the same time, supporting projects around the site are also accelerating. The road widening of Lan'an Road is basically complete, and the underpass tunnel is 50% complete; the earthwork and stonework of the Xueyuan Road subgrade is wrapping up, and the underpass tunnel is 60% complete. The already-opened L Line and the Sandaoqiao section of Xueyuan East Road have effectively eased regional traffic pressure.

     Up to now, the number of river-crossing bridges in the central urban area of Luzhou has increased to 10, and the 52.5-kilometer Second Ring Road has been fully connected into a ring. The "two rings, one vertical, one horizontal" metropolitan framework has taken initial shape. The length of roads in built-up areas has reached 1,113 kilometers, with a road network density of 8.02 kilometers per square kilometer. The 10-minute living circle in urban areas has been fully established, and urban clusters are now rapidly interconnected.
