In the realm of modern infrastructure, the choice of bridge design and materials plays a crucial role in ensuring safety, durability, and cost-effectiveness. Among the various types of modular bridges available, the 321-Type Modular Bailey Bridge stands out for its unique features and applications.

The GWD Long-Span Modular Steel Bridge represents a quantum leap in prefabricated bridge technology, achieving previously unimaginable 180-meter spans through innovative engineering. This system combines factory precision (≤3mm assembly tolerance) with rapid on-site deployment (8m daily progress), while supporting combined highway and rail loads up to 10,000 tons.
