en.Wedoany.com Reported - Recently, the last pile foundation for the G318 overpass crossing the G233 interchange, part of the first bid section of the G318 Shanguan to Langxi Boundary reconstruction and expansion project, was successfully poured, marking the completion of all 24 pile foundations for the substructure of this critical node project. The highway construction project is located in Anhui Province, China. The G318 overpass crossing the G233 interchange adopts a separated design featuring a mainline overpass with auxiliary roads at grade. The mainline spans the planned G233, while the auxiliary roads are equipped with channelized traffic and signal control. The estimated investment for this single interchange is approximately 70 million yuan.

This interchange is the core controlling project of the first bid section, and its construction progress directly impacts the overall project timeline and the target opening date. The project scope includes new interchange ramps, mainline acceleration and deceleration lanes, and widened pavement sections in transition areas. Upon completion, it will enable rapid transfer between G318 and G233, improving the connectivity of the regional national and provincial trunk road network.

The first bid section of the G318 Shanguan to Langxi Boundary highway reconstruction project spans a total length of 15.8 kilometers and is being advanced in two phases. The main construction work for the 10.2-kilometer Phase 1 section has been fully completed, with finishing work on ancillary projects such as safety barriers and landscaping currently underway. For the 5.6-kilometer Phase 2 section through the forest park area, steady progress is being made, with roadbed engineering reaching 50% completion and bridge and culvert works at 30%.

The project task force will focus on the target of completing the main construction work by October 2026, urging the construction units to seize favorable weather windows, deploy manpower and machinery, optimize work sequence coordination, and accelerate the highway construction progress.
