The Bailey trestle bridge, also known as a temporary access bridge or a trestle bridge, is a structure built to provide access for construction activities. It is mainly used during the construction of large-scale infrastructure projects such as bridges, ports, and dams. For example, when building a long-span sea-crossing bridge, the trestle bridge allows construction vehicles and equipment to transport materials and workers to the construction site over water or difficult terrains.

• High Strength and Load-bearing Capacity: Designed with robust structure using vertical piles and horizontal beams/trusses for excellent load-bearing capacity to support heavy construction equipment.
• Versatility and Adaptability: Suitable for various environments including water bodies with adjustable height according to water level and flood-proofing requirements.

• Facilitating Loading and Unloading: Serves as temporary loading/unloading platform for construction materials transported by barges and ships.
• Cross-Valley or River Access: Essential for dam construction and hydraulic structures in valleys or across rivers.
• Temporary Support for Heavy Equipment: Provides support structure for lifting and positioning large industrial equipment.

• Adaptability: Suitable for various terrains including water, valleys, and uneven ground with adjustable height and anti-corrosion options.
• Load-Bearing Capacity: Designed to support heavy vehicles, machinery, and materials with customizable capacity based on project requirements.
