The main bridge of Yachang No. 2 Bridge was successfully closed.

　　Recently, the main bridge of Yachang No. 2 Bridge, constructed by the Fourth Company of CCCC First Highway Engineering Co., Ltd. under the Guangxi Lewang No. 3 bid section, was successfully closed.

　　The Leye–Wangmo (Leye section) Expressway is an important component of the "Guangxi Expressway Network Plan (2018-2030)". The route has a total length of 59.4 km, is a dual-carriageway four-lane expressway with a design speed of 100 km/h, and the bridge-tunnel ratio of the main line reaches 79.1%, making it the expressway with the highest bridge-tunnel ratio in Guangxi at present. Among this, the Lewang No. 3 bid section has a total route length of 13.8 km, including 13 major bridges and 2 extra-large bridges, with a bridge-tunnel ratio of 72% along the entire line. The right carriageway of the Yachang No. 2 Bridge under this project is 629 m long in total, and the left carriageway is 589 m long in total. During construction, the project team overcame difficulties such as drought and water shortage and the difficult transportation of materials and equipment, adopted the double form traveler hanging bracket construction technique, continuously collected and analyzed various data including closure temperature, elevation and main girder axis, and verified and optimized the concrete mix proportion based on monitoring data, thereby completing the closure of the main bridge with high quality.

　　After the expressway is completed, it will become an important inter-provincial corridor for convenient connectivity between Guizhou and Guangxi. The drive from Leye county seat to the provincial border is expected to be shortened from 2 hours to 0.5 hours, benefiting 180,000 people along the route, and is of great significance for accelerating the development of resources along the route, promoting regional economic and social development, and achieving complementary advantages.
