Expressway-marked Flatlands

Updated:2021-12-16 | By: Academy of Contemporary China and World Studies

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

貴州省是典型的喀斯特地貌,是中國唯一沒有平原支撐的省份,海拔落差大,山高谷深,交通成為制約經(jīng)濟社會發(fā)展的瓶頸。高速公路網(wǎng)絡改變了這一切,山地貴州仿佛成了平原。

2001年12月,貴州開通第一條高速公路--凱麻高速,里程為50.9千米。2015年年末,貴州率先在中國西部實現(xiàn)縣縣通高速公路,通車里程達到5128千米。截至2020年年末,貴州全省高速公路通車里程達7607千米,綜合密度居全國前列。
