The Beijing–Hong Kong and Macau Expressway, designated as G4 and commonly referred to as the Jinggang'ao Expressway is a 2272.65adj=midNaNadj=mid-long expressway that connects the Chinese cities of Beijing and Shenzhen, in Guangdong province, at the border of Hong Kong. The expressway terminates at the Huanggang Port Control Point in Shenzhen, opposite the Lok Ma Chau border control point in Hong Kong.
The expressway begins at the interchange with the southwestern section of 3rd Ring Road, known as Liuheqiao Bridge, in Beijing. At first it heads west, passing through the 4th Ring Road at Yuegezhuang, and then approaches a heavily industrialized area, the Xidaokou area near Shougang. On the way out of Beijing the expressway passes through the famous Luguoqiao area, home of the Marco Polo Bridge and Wanping, marking where the Second Sino-Japanese War began in 1937. The expressway also links Beijing to the Zhoukoudian Peking Man cave, as well as Yunju Temple.
The expressway is free of charge in Beijing urban area, and then becomes tolled after Dujiakan Toll Station. The expressway then heads south, passing through Liangxiang in Fangshan, before leaving Beijing near Liulihe.
The expressway ends at Huanggang Port, Shenzhen, connected with the road to Hong Kong.
The expressway began as the Jingshi Expressway linking Beijing to Shijiazhuang, Hebei. Construction of this 2700NaN0 section began in April 1986 and was opened in full in November 1996. This first section was previously numbered G030.
