On March 30, the 25 - meter T - beam erection of Zengjiagou Bridge in the TJ5 bid section of the Zizhong - Leshan Expressway, which is constructed by China Railway Guangzhou Engineering Bureau, was successfully completed. This kick - started the construction of the upper - structure of the bridges on the Zizhong - Leshan Expressway (China Railway section), laying a solid foundation for the subsequent construction of the bridge deck system and ancillary projects.

Zengjiagou Bridge is located in Jiyi Town, Jingyan County and is built to span a wide and gentle valley. The bridge is 260.5 meters long and requires the erection of 141 25 - meter T - beams. The T - beam erected this time is the No. 4 beam of the 10th span on the left - hand side. To ensure the smooth progress of the first - beam erection work, the project department organized scientifically and managed meticulously. Through effective measures such as optimizing the construction plan, strictly controlling the process, and strengthening on - site safety supervision, the precise hoisting and stable erection of the first beam were guaranteed.

The relevant person in charge of the project department said that the successful erection of the first beam has accumulated valuable experience for the subsequent beam - erection tasks. Taking this milestone as an opportunity, the project department will further strengthen communication, coordination, and resource allocation, strictly follow the requirements of standardized management specifications, and fully promote the safe and steady progress of various construction tasks, striving to achieve the project's annual production target.

The Zizhong - Leshan Expressway starts near Ranfang Village, Zizhong County, Neijiang City, connecting to the Xiamen - Chengdu Expressway and the Zizhong - Tongliang (Sichuan section) Expressway under construction at the same time. It passes through Weiyuan County in Neijiang City, Renshou County in Meishan City, and Jingyan County in Leshan City, and ends at Mouzi Town, Shizhong District, Leshan City. It connects to the Tianfu - Meishan - Leshan Expressway under construction at the same time and links to the Leshan - Yingjing Expressway. After its completion and opening to traffic, it will further improve the regional road network, strengthen the connection of the road network among the urban agglomerations in southern Sichuan, and help Leshan accelerate the construction of an important regional transportation and logistics hub in the province.
