Project Overview
This gas pipeline relocation is necessitated by the highway expansion of the Fuquan Expressway connector and planned Luocheng Road routing in Cangshan District, Fuzhou City. Approximately 1,450m of existing pipeline is encroached by planned ramps and roundabouts, with some sections directly beneath highway interchange pile foundations. The new route spans 1,821.7m (Pile AP-01 to AP-52).
