The Beijing–Taipei Expressway (Chinese: 北京–台北高速公路; pinyin: Běijīng–Táiběi Gāosù Gōnglù), designated as G3 and commonly known as the Jingtai Expressway (Chinese: 京台高速公路; pinyin: Jīngtái Gāosù Gōnglù), is a partially completed Chinese expressway that, if fully constructed, would connect the People's Republic of China with Taiwan. Currently, the expressway is complete from Beijing to Fuzhou, Fujian, and is fully complete in Mainland China except for a small section in Fujian which is under construction.
