The construction of steel-truss-girder cable-stayed bridges is essential to overcoming the challenges of transportation in mountainous regions, making them a preferred choice for long-span highway bridges. However, most previous research has focused on railway or rail–road applications, with limited attention paid to highway-specific designs. This paper begins with an analysis of the use and characteristics of bridges in mountainous terrains based on an investigation of 1356 bridges. A steel-box-girder cable-stayed bridge scheme is then propos...
