Modular bridges are pre-fabricated structures designed for quick and easy assembly. They consist of standardized components that can be transported and assembled on-site, making them ideal for temporary or permanent use. These bridges can be adapted to various spans and load requirements, providing flexibility in design. The use of modular bridges can significantly reduce construction time and costs compared to traditional bridge-building methods. They are often employed in emergency situations, such as after natural disasters, to restore access quickly. Additionally, modular bridges can be reused or relocated, contributing to sustainable infrastructure development.
