National Expressway 1

National Expressway 1, also known as the Trans Golden Arc Highway (Zhenian: 금호고속도로; Geumho Gosokdoro), is the oldest and single most heavily-traveled in the National Expressway network of Zhenia. Traversing through much of the Golden Arc region as well as adjoining areas from Gwangseong in Gyeongcheon Province to Zhuhae in Balhae Province, it passes through many of the largest Zhenian cities and industrial centers. It is given the route number 1, in light of the historical and economic significance of the route to the nation. It is widely considered the single most important expressway in the nation, hence earning its nickname 'the artery of Zhenia'. Traversing through an entire length of 10,185.87 kilometers all the way from Gwangseong to Zhuhae, it is also one of the longest expressway in the nation, with a maximum speed of around 120 km/h enforced by speed cameras across most of its segments.
