2. Construction and Design

Modular Components:
The Bailey Bridge is known for its modular construction. It consists of prefabricated components, including:

· Panels: Made of steel, these panels are the primary load-bearing elements.

· Transoms: Horizontal elements that support the bridge deck.

· Bearers: Longitudinal members that distribute the load across the bridge.

Assembly:
The assembly process is straightforward and can be completed with minimal tools. The bridge is constructed by connecting the modular components together, allowing for quick erection and disassembly. This makes it ideal for temporary structures and emergency situations.
