The CB450 Delta Bridge is a purpose-built prefabricated highway steel bridge engineered to overcome large-span obstacles—including gullies, rivers, and deep ravines. What sets it apart is its compatibility with Bailey Bridge components, which can be integrated as cantilevers for efficient erection. Designed to meet long-term infrastructure needs, it functions seamlessly as a permanent bridge for various grades of road construction, balancing durability, flexibility, and highway-grade performance.
Core Advantages
Long-Span Flexibility: Offers a single span of 36–81m as standard, with each section extendable by 2.225m—adapts to large gap obstacles without compromising structural stability, eliminating the need for multiple intermediate supports.
Bailey Bridge Component Compatibility: Supports erection using Bailey Bridge components as cantilevers, leveraging existing modular systems to reduce on-site construction complexity and shorten project timelines.
Highway-Grade Load Capacity: Complies with HS20-44, HA, HB, and Highway Grade I standards, with a maximum tacked load of 60t—safely accommodates heavy-duty highway traffic, including commercial trucks and passenger vehicles.
Dual Deck Options: Available with steel or concrete bridge decks, allowing customization based on project budgets, traffic volume, and long-term durability requirements (concrete decks excel in high-wear, heavy-traffic scenarios).
Customizable Roadway & Sidewalks: Features a standard 4.2m single lane or 7.35m double lane roadway (adjustable for unique needs), plus optional sidewalks in 1m, 1.2m, or 1.5m widths—meets pedestrian safety standards for urban or suburban highway projects.

Application Scenarios
Permanent Highway Construction: Serves as a permanent crossing for new highway projects—ideal for spanning large gullies or rivers in rural, suburban, or urban areas, complying with Highway Grade I performance requirements.
Infrastructure Upgrades: Replaces aging or temporary bridges in highway networks, offering a durable steel/concrete deck solution that supports heavy commercial traffic (HS20-44 standard) for decades.
Post-Disaster Permanent Reconstruction: Provides a long-term replacement for bridges damaged by floods, earthquakes, or storms—its prefabricated design accelerates reconstruction while ensuring permanent usability.
Remote Area Connectivity: Bridges large gaps in remote or underdeveloped regions, enabling reliable highway access for communities, mining operations, or industrial sites—supports both passenger traffic and heavy equipment transport.
Support & Service
Custom Design Consultation: Works with clients to adjust span lengths, deck materials, and sidewalk configurations to match specific site conditions (e.g., high-water zones, seismic areas).
Erection Expertise: Provides on-site guidance for integrating Bailey Bridge components, plus training for construction teams to ensure efficient, safe assembly.
Long-Term Maintenance Support: Supplies replacement parts (truss components, deck panels, fasteners) and offers periodic inspection services to extend the bridge’s service life.
Compliance Documentation: Delivers full certification packages, including load test reports, Highway Grade I compliance records, and material durability certifications, to streamline project approval.
