The Bailey trestle bridge is composed of standardized, prefabricated steel panels and components that can be easily assembled on-site. These modular elements include chords, web members, transoms, and bracing, which can be quickly connected to form the bridge structure.

The Bailey Trestle Bridge, as a variant of the Bailey platform, has been studied and incorporated into engineering curricula and research programs. It serves as a case study for understanding the principles of modular construction, load-bearing analysis, and the design considerations for temporary bridge structures.

The trestle design, in particular, provides insights into the engineering challenges and solutions for longer-span temporary bridges. The Bailey Trestle Bridge's unique design features, such as its ability to span longer distances and support heavier loads, have made it a valuable and widely-used solution in various applications, from military operations to emergency response and infrastructure development in remote or underdeveloped regions.

• Transportability: The modular components of the Bailey trestle bridge can be easily transported, often by truck or rail, to the construction site. The lightweight and compact nature of the individual elements facilitate efficient transportation and handling.
• Reusability: The Bailey trestle bridge components are designed to be disassembled, transported, and reassembled at different locations. This makes the Bailey bridge a cost-effective and efficient solution, as the same materials can be used repeatedly for various temporary bridge projects.
