G1 Expressway runs from Beijing to Harbin, abbreviated as the Jingha Expressway, and has been fully constructed as an expressway. The G1 route includes: Beijing, Tangshan, Qinhuangdao, Jinzhou, Shenyang, Siping, Changchun, and Harbin, with a total length of 1,280 kilometers. The Jingha Expressway commenced construction in September 1996 and was fully opened to traffic on September 15, 2000. An expressway, abbreviated as 'highway,' refers to a road specifically designed for high-speed vehicle travel. Expressways have different regulations in different countries, regions, eras, and academic fields. Countries and regions around the world have their own construction standards for expressways, with no unified model. The expressway systems vary between different countries and regions, with some countries and regions including certain controlled-access, non-full-interchange direct arterial roads as part of their expressway systems.
