Types of Temporary Bridges
Every jobsite is different, and so is the bridge it requires. Zavza Seal provides a range of temporary bridge systems designed to support safe, reliable access for every kind of construction environment. Each bridge is engineered to meet NYSDOT safety criteria and perform under New York’s demanding weather and terrain conditions.
- Bailey Bridge: A Bailey Bridge is a modular steel truss bridge designed for fast assembly and high strength. Known for its proven reliability, a Bailey Bridge can be quickly installed to restore access after floods, during road reconstruction, or in remote construction zones. Contractors and municipalities trust Bailey Bridges for their versatility, durability, and ability to handle heavy construction loads.
- Acrow Bridge: An Acrow Bridge is a modern version of the classic panel bridge system engineered for greater span lengths and heavier traffic. Built with precision-manufactured steel modules, an Acrow Bridge provides a strong, reusable solution for temporary detours, site access, or disaster recovery. Its speed of installation and low maintenance make Acrow Bridges a preferred choice for both short- and long-term projects.
- Steel Girder Bridge: A Steel Girder Bridge offers a simple yet powerful temporary crossing option using prefabricated girders and decking. Ideal for construction detours or equipment access, a Steel Girder Bridge provides stability, long service life, and cost efficiency. Its straightforward design allows fast deployment and removal without compromising structural safety or load capacity.
- Pontoon Bridge: A Pontoon Bridge is a floating structure that supports vehicular or pedestrian traffic over water using modular pontoons or floats. Perfect for emergency use or temporary crossings, a Pontoon Bridge can be assembled rapidly and adjusted for varying water levels. These bridges are lightweight, transportable, and essential for keeping projects moving in flood-prone or remote areas.
- Temporary Truss Bridge: A Temporary Truss Bridge uses a high-strength steel framework to span long distances where other bridge types may not be practical. Designed for construction access, rail or road detours, and heavy transport routes, a Temporary Truss Bridge combines speed, capacity, and adaptability. Its modular nature allows quick installation while meeting strict engineering and safety standards.
From modular bridge components to temporary access spans, Zavza Seal designs every structure for the specific demands of your site, ensuring compliance, stability, and efficiency from setup to removal.
Engineering Standards & Load Ratings
At Zavza Seal, every temporary bridge is engineered for load-bearing precision and regulatory compliance. Our designs follow AASHTO LRFD Bridge Design Specifications to ensure structural integrity under real-world conditions.
We calculate load capacity, axle loads, live load distribution, and deflection limits according to both NYSDOT design standards and ASTM A709 structural steel specifications. Each bridge undergoes strict safety inspections, certified weld verification, and on-site load testing to confirm it meets required performance levels.
Our engineers evaluate:
- Axle Load Distribution: Ensuring uniform stress across bridge panels and trusses.
- Live Load Ratings: Based on anticipated traffic, equipment weight, and frequency.
- Allowable Deflection Limits: Maintaining deck stability under heavy loads and repetitive use.
- Corrosion & Fatigue Resistance: Using ASTM-certified materials and coatings.
Each bridge is field-tested and certified, providing the peace of mind that your access solution is safe, compliant, and engineered for endurance.
Installation Process: From Design to Deployment
Building a safe and reliable temporary bridge requires precision planning and coordination. At Zavza Seal, we manage every phase from engineering design to on-site assembly to ensure your project stays compliant, on schedule, and fully operational.
- Site Survey & Geotechnical Review: Our process begins with a detailed site assessment to evaluate soil conditions, elevation, and load requirements. This ensures the foundation and bridge design are tailored to your terrain and equipment.
- Bridge Design & Permitting: Our engineering team designs to AASHTO and NYSDOT specifications, securing any required permits for public or private construction sites.
- Fabrication or Modular Sourcing: Depending on the project, bridges are custom-fabricated or sourced from our inventory of modular steel and timber systems for rapid deployment.
- Transport & Assembly: We use cranes, spreader bars, and pile supports to position components efficiently, minimizing disruption to ongoing operations.
- Anchoring, Decking, and Safety Rails: Every structure is fitted with reinforced anchoring systems, durable decking, and OSHA-compliant safety rails for worker protection.
- Post-Installation Inspection & Certification: Once installed, each bridge undergoes a full safety inspection and load certification by our structural engineers before being released for use.
Most temporary bridges can be installed in under 72 hours, depending on size and site complexity, ensuring your access routes stay open when timing matters most.

Case Study: Pedestrian Walkway Bridge Installation in New York
Problem:
A busy New York site faced serious safety and accessibility issues. Pedestrians, workers, and site visitors were forced to cross active construction zones with no secure pathway in place. The client needed a temporary bridge that could handle constant foot traffic, withstand harsh weather, and integrate seamlessly into the existing site, all while minimizing downtime and maintaining compliance with safety regulations.
Solution:
Zavza Seal LLC engineered and installed a temporary pedestrian walkway bridge built for strength, stability, and longevity. Using 18-inch concrete columns embedded 50 inches deep, the team created a solid foundation. Brackets with shims and gutters provided perfect alignment and efficient drainage, while hurricane ties and floor joist brackets added critical reinforcement against wind and vibration. The bridge was secured with a ledger attachment system and finished with treated wood decking for durability and weather resistance.
The completed structure delivered a safe, accessible, and fully compliant crossing, improving site flow and protecting workers and pedestrians alike. Zavza Seal’s quick turnaround and precision engineering proved why it remains a trusted partner for temporary bridge construction across New York.
