The Hanging – Wall Highways in Taihang Mountains: Man – made Wonders Inscribed on Steep Cliffs

I. Introduction

In the vast land of China, there is a road that winds around the cliffs of the Taihang Mountains like a giant dragon. This is the Hanging – Wall Highway in the Taihang Mountains. The birth of this highway is not only a feat in the history of transportation but also a symbol of the indomitable spirit of humanity. It shuttles through the precipitous mountains, connecting the deep mountains with the outside world, and composing a soul – stirring song of struggle among the lofty mountains.

II. Geographical Location and Geological Background

(I) Geographical Coordinates and Regional Scope of the Taihang Mountains

The Taihang Mountains, an important mountain range and geographical boundary in eastern China, start from the Western Hills of Beijing in the north and extend southward to the Wangwu Mountains at the junction of Henan and Shanxi provinces. It runs in a northeast – southwest direction, stretching for more than 400 kilometers. It spans four provinces and municipalities, namely Beijing, Hebei, Shanxi, and Henan, separating the North China Plain from the Shanxi Plateau.

(II) Unique Geological Structure

The geological structure of the Taihang Mountain area is complex and diverse, mainly composed of ancient metamorphic rocks, limestone, and sandstone. During the long geological evolution process, strongly influenced by plate movements, the Taihang Mountains have experienced multiple crustal uplifts and fault activities, forming the current steep terrain and criss – crossed canyons. The mountain rocks are hard and have well – developed joints, which have brought great challenges to the construction of the hanging – wall highways but also provided a certain foundation for the stability of the roads.

III. Historical Evolution of the Hanging – Wall Highways

(I) Background of Construction

In the past, transportation in the Taihang Mountain area was extremely inconvenient. The mountains, like natural barriers, isolated the mountain villages from the outside world. Local residents had great difficulties in traveling, and the transportation of goods was even more arduous, severely restricting economic development and the improvement of living standards. In order to change this situation and lead a better life, local residents came up with the idea of building a road on the cliffs.

(II) Construction Process

1. Xiyagou Hanging – Wall Highway: It is the earliest and most time – consuming hanging – wall highway among those in the Taihang Mountains. In 1962, under the leadership of the Party branch, the villagers of Xiyagou Village vowed, “We will fight hard for ten years and spare no effort to build a road leading to the outside world,” and began the arduous road – building journey. Without modern mechanical equipment, they chiseled inch by inch on the cliffs with only hammers, chisels, and their bare hands. After 30 years, they finally completed this 7.5 – kilometer – long hanging – wall highway in 1991.
2. Guoliang Hanging – Wall Highway: In 1972, 13 villagers in Guoliang Village, led by Shen Mingxin, sold goats and Chinese yams to raise funds to buy steel hammers and files. Without electricity and machinery, they relied entirely on manual labor. After 5 years, they carved out this 1250 – meter – long highway on the cliffs. During the construction process, the villagers tied ropes around their waists and worked in the air, blasting rows of holes on the cliffs, and then chiseling with steel chisels and hammers. The thrilling degree is unimaginable.
3. Hongtiguan Hanging – Wall Highway: It was built in the 1960s. At that time, the people of Hongtiguan Township, Pingshun County, in order to open up a connection with the outside world, built the road with simple tools under extremely difficult conditions. This highway is 10.5 kilometers long, with a narrow road surface and a large slope. The scenery along the way is magnificent, witnessing the spirit of the people’s fearlessness and courage in those days.
4. Chenjiayuan Hanging – Wall Highway: Its construction started relatively late, in 1995, and was completed in 3 years. During the construction of this highway, the local terrain and water resources were fully utilized, running along the cliff and accompanied by a reservoir, forming a unique landscape.

IV. Architectural Features of the Hanging – Wall Highways

(I) Unique Excavation Method

The hanging – wall highways are excavated using a combination of the “segmented” and “zig – zag” methods. Due to the steep mountains, it is impossible to excavate a straight road at one time. Therefore, the workers excavated tunnels along the trend of the cliffs in sections and then connected them through zig – zag sections. When excavating the tunnels, holes were first drilled on the cliffs, then explosives were placed for blasting, and finally, tools such as steel chisels and hammers were used to trim the inner walls of the tunnels, gradually widening and deepening them. This excavation method can not only adapt to the complex terrain but also reduce the project volume and construction difficulty.

(II) Unique Lighting Design

To solve the problem of insufficient lighting in the tunnels, the hanging – wall highways adopt a unique side – window design. At regular intervals, a rectangular side – window is excavated on one side of the tunnel. These side – windows not only provide natural light for the tunnels, enabling drivers to see the road conditions clearly during driving, but also become unique landscapes on the highway. Looking from a distance, the side – windows on the hanging – wall highway are like the scales of a giant dragon, shining brightly.

(III) Harmonious Co – existence with Nature

The construction of the hanging – wall highways fully considers the harmonious co – existence with the natural environment. Although the excavation of the highways has changed part of the appearance of the mountains, the workers try their best to minimize the damage to the surrounding ecological environment. A large number of trees and flowers are planted along the highways, which not only beautify the environment but also prevent landslides and soil erosion. In addition, the hanging – wall highways complement the surrounding mountains, canyons, rivers, and other natural landscapes, forming a unique scenic line.
