At present, the expressway network with the national expressway as the main body has covered 98.8% of the urban population of more than 200000 cities and prefecture level administrative centers, connecting about 88% of the county-level administrative regions and about 95% of the population; Ordinary national roads basically cover administrative regions at or above the county level and border ports opened all year round, effectively connecting important towns, industrial parks, transportation hubs and tourist attractions. It is reported that the national highway network, including the national highway network and the ordinary national highway network, is an important part of the foundation and main framework of the national comprehensive three-dimensional transportation network. By the end of 2021, 117000 kilometers of national highways and 257700 kilometers of ordinary national highways have been completed. The national highway network plan jointly issued by the national development and Reform Commission and the Ministry of transport proposed that by 2035, the total size of the national highway network will reach about 461000 kilometers, including about 162000 kilometers of national highways and about 299000 kilometers of ordinary national highways. The meeting also introduced the high-quality development of rural roads. The total mileage of rural roads increased from 3.564 million kilometers at the end of 2011 to 4.466 million kilometers at the end of 2021, with a net increase of more than 900000 kilometers in 10 years. In recent years, the technological innovation of highway construction has achieved fruitful results, and the highway survey and design technology represented by digital maps, geological remote sensing, computer-aided design and simulation, and the application of Beidou system is making continuous progress; The technology of highway construction in soft soil, loess, frozen soil and desert areas is constantly maturing and improving; Breakthroughs have been made in technologies and equipment related to super long-span bridges, super long tunnels in mountain areas, submarine immersed tunnels, large-diameter shield tunnels, etc. In the next step, relevant departments will, in accordance with the planning objectives and tasks, focus on promoting the implementation of key projects, strengthening the coordination and connection with other modes of transportation, improving the green and intelligent level of highway construction, and promoting the safety and reliability of highway facilities network, so as to promote the construction of modern and high-quality national highway network.
