Winding in a typical karst mountainous area with deep trenches and steep slopes, the Jingxi-Napo or Jingna expressway, known as one of the most beautiful expressways in the world.

It opens up lofty mountains and ridges, crosses deep gullies, passes through stone forests and lavas, to connect to the banks of the Qinzhou Bay.

The expressway's total length is 90.417 kilometers.

It adopts two-way and four-lane standard construction with asphalt concrete pavement.

The roadbed is 26 meters wide, and the designed driving speed is 100 km per hour.

To reduce damage to the local natural landscape, builders adopted a series of measures to remove as many "scars" as possible, which were caused by blasting rocks and weakened the artificial traces.

By removing scars, the appearance of the slope becomes more harmonious with the surrounding environment.

When driving on the road, you can see tunnels with local characteristics every few kilometers.

The tunnel door combines local humanities, history, customs, and design elements from Zhuang dances and musical instruments, which are demonstrated in painting and embossing art forms.

It fully reflects the cultural customs of ethnic groups in Guangxi. The expressway has one large-scale hub interchange in Jiuzhou plus four additional interchanges and two service areas in Jingxi and Napo.

Due to its location on the edge of the Yunnan-Guizhou Plateau, the terrain is complex and the proportion of bridges and tunnels accounts for 28 percent of the roadway, making construction difficult.

The opening of the expressway to traffic ends Jingxi and Napo's history of inability to reach one another via expressway.

It is important to improve the layout of the Guangxi expressway network, strengthen the economic and transportation links between western Guangxi and the southwest and eastern coastal areas.

The expressway plays a key role in promoting the coordinated development of western Guangxi's economy and helps to build a major China-ASEAN international channel.
