When constructing bridges in mountainous areas, due to the complex terrain, changeable geological conditions and harsh climatic conditions, special attention should be paid to the following aspects:

1. Complex geological conditions
- **Detailed geological survey**: Mountainous areas have changeable terrain and complex geological structures, often including multiple rock types and soil layer structures. Detailed geological surveys must be carried out before construction to identify the engineering geological characteristics of the proposed site to ensure the rationality and safety of the bridge foundation design.
- **Geological disaster prevention**: Mountain construction faces the threat of multiple geological disasters, such as landslides, mudslides, rock collapses, etc. Special reinforcement measures, such as prestressed anchor rods and pile foundation reinforcement, need to be taken during construction to ensure the stability and safety of the bridge.

2. Harsh construction environment
- **Extreme climate response**: Mountain construction often faces extreme climatic conditions, such as severe cold, high temperature, strong wind, etc. Construction workers need to take corresponding protective measures and ensure the performance of construction materials in extreme climates.
- **High-altitude construction**: In high-altitude areas, construction workers need to deal with altitude sickness, such as hypoxia, headaches, fatigue, etc. In addition, attention should be paid to the threat of strong ultraviolet radiation to the health of construction workers.
- **Narrow construction site**: The complex terrain in mountainous areas and the narrow construction site bring great inconvenience to the transportation of materials and the layout of construction equipment. A detailed traffic organization plan needs to be formulated to reasonably arrange the route and time of construction vehicles.

3. High construction technology requirements
- **Precise design and construction**: Mountain bridge construction requires high accuracy and innovation in bridge structure design, and precise control during the construction process is essential to ensure that the bridge can remain stable under extreme climate and geological conditions.
- **Material and equipment selection**: Construction materials need to adapt to the climate and geological conditions in the mountains. At the same time, construction equipment needs to have good mobility and adaptability to cope with complex terrain.

4. Huge amount of engineering
- **Reasonable planning of construction period**: The amount of engineering for mountain bridge construction is huge and the construction period is long. A scientific and reasonable construction plan needs to be formulated, taking into full consideration natural factors such as terrain and geology, and combining the characteristics and difficulties of each construction stage to formulate a reasonable construction schedule.
- **Fund management**: The construction of highway bridges in mountainous areas requires more urgent funds. Contractors need to carefully plan capital operations and allocate resources reasonably to ensure that the project is carried out in an orderly manner with sufficient funds.

5. Safety and environmental protection
- **Construction safety**: Construction workers must wear safety helmets and safety belts, and it is strictly forbidden to work on the shelves after drinking. When using a crane to lift and remove Bailey piers, a special person should be assigned to direct the crane, and it is strictly forbidden for the crane arm to collide with the Bailey beam and its foundation.
- **Environmental protection**: Construction in mountainous areas needs to consider ecological protection and environmental protection issues, such as vegetation protection and water source protection, to mitigate the impact on the surrounding ecological environment.

Through the above measures, various challenges in mountain bridge construction can be effectively addressed to ensure safe, efficient and environmentally friendly construction.
