Expressway-marked Flatlands
Guizhou has typical karst landforms. It is the only province in China that has no flatlands, but high mountains, deep valleys and wide elevation differences. Inadequate transportation had been impeding the province's economic and social development, but the creation of an expressway network changed everything. Mountainous Guizhou seems to have been turned into a province of flatlands.
In December 2001, Guizhou saw the first ever expressway - 50.9 kilometer Kaili-Majiang Expressway put into service. At the end of 2015, Guizhou was the first province in western China to give every county access to expressways whose total length stood at 5,128 kilometers. As of the end of 2020, the length of expressways open to traffic across the province reached 7,607 kilometers and its expressway network density was among the country's top levels.
高速平原
贵州省是典型的喀斯特地貌,是中国唯一没有平原支撑的省份,海拔落差大,山高谷深,交通成为制约经济社会发展的瓶颈。高速公路网络改变了这一切,山地贵州仿佛成了平原。
2001年12月,贵州开通第一条高速公路--凯麻高速,里程为50.9千米。2015年年末,贵州率先在中国西部实现县县通高速公路,通车里程达到5128千米。截至2020年年末,贵州全省高速公路通车里程达7607千米,综合密度居全国前列。
