Bailey bridge piers serve as the support structures that hold up the bridge deck and transfer the weight of the bridge and any loads crossing it down to the ground or riverbed below.

The Bailey bridge pier is composed of foundation, pier body, top support and bridge span fixing device. The foundation consists of a base plate and anchor bolts; The pier is composed of 1m truss, Angle brace, HD321 Bailey panel standard truss, vertical cross brace 1, vertical Raker, vertical cross brace 2, horizontal wind structure.

The modular design of Bailey bridge piers allows the height and number of trestle legs to be adjusted as needed to accommodate different gap widths and depths. Additional intermediate piers can also be added for longer bridge spans.

• Lateral Stability: The diagonal sway bracing members provide strong lateral support to the piers.
• Adjustable Height: The number and length of the trestle legs can be varied to accommodate different gap depths. This flexibility allows Bailey bridges to span a wide range of obstacles.

These features combined make the Bailey bridge pier design highly adaptable, versatile, and well-suited for temporary crossings in challenging environments. The portability and speed of assembly were critical factors in the widespread use of Bailey bridges during WWII and other conflicts.
