The Shanghai–Chengdu Expressway (Chinese: 上海－成都高速公路; pinyin: Shànghǎi-Chéngdū Gāosùgōnglù), designated as G42 and commonly referred to as the Hurong Expressway (simplified Chinese: 沪蓉高速公路; traditional Chinese: 滬蓉高速公路; pinyin: Hù-Róng Gāosùgōnglù) is an east–west bound expressway that connects the eastern metropolis of Shanghai to Chengdu, the capital city of Sichuan. The expressway passes through six provinces and serves major cities such as Suzhou, Wuxi, Changzhou, Nanjing, Hefei, Wuhan, and Yichang. The eastern terminus of G42 is at the Wuning Road Interchange of Shanghai Middle Ring Road. At its western terminus, the expressway intersects the East 3rd Ring Road and connects East Erxianqiao Road in Chenghua District, Chengdu. The expressway spans 1,960 km (1,220 mi) in length.

With the completion of the remaining Chongqing–Yichang segment of the expressway construction in December 2014, the entire length of the Shanghai-Chengdu Expressway officially opened to motorists.

G42 is the principal highway of Yangtze Economic Corridor and therefore reportly facilitates 46.6 percent of the country's gross domestic product, making it one of the most economically active expressways in the world, like Interstate 95, although both US East coast and the Yangtze Economic Corridor is served by numerous other highways and means of transport.
