As the first mountain-traversing expressway in Sichuan Province, the project expressway crossed geo-technically difficult and complicated terrain. To cope with various technical difficulties and challenges, Sichuan Provincial Transportation Department (SPTD) and SPECL initiated 14 technical studies associated with the project expressway's construction. Of the 14 studies, two were awarded state patents and eight were acknowledged as achievements at the provincial and ministry level. The application of these technical research products in the project expressway's construction generated significant social and economic benefits. For example, technical innovations in the study of road construction on Xigeda stratum has been widely used in constructing other road projects, allowing significant cost savings. Other ongoing road projects also benefitted from these studies. The initiation and wide application of the knowledge products are commendable.
