The Shanghai–Jinshan Expressway, commonly referred to as the Hujin Expressway (Chinese: 沪金高速公路; pinyin: Hùjīn Gāosù) and designated S4, is an expressway in the city of Shanghai, China. It runs generally in a north-south direction from the Xinzhuang Interchange, a large interchange with the Outer Ring Expressway, the G60 Shanghai–Kunming Expressway, the G92 Hangzhou Bay Ring Expressway, and Humin Elevated Road in Minhang District to Jinshan District, ending at an interchange with the G15 Shenyang–Haikou Expressway. The expressway is tolled south of the Zhuanqiao Service Area in Minhang District, between the exits to Yindu Road and the Shanghai–Jiaxing–Huzhou Expressway.
