Elevating Bridge Inspection Excellence for Engineers
The Anderson UnderBridge Advantage for Engineering Firms
Through close collaboration with inspection teams nationwide, we’ve developed specialized solutions that align perfectly with the workflow and documentation needs of bridge inspection engineers at professional firms. When you partner with Anderson UnderBridge, you gain access to:
Our certified operators handle equipment deployment and operation while your bridge inspection engineers focus exclusively on doing their work. This division of responsibilities maximizes efficiency and allows your team to concentrate on their core expertise.
Built-in electrical connections support laptops, testing equipment, and other electronic devices essential for modern inspection protocols. Clean power ensures reliable operation of sensitive measurement and documentation tools.
Our platforms deploy in minutes, not hours, reducing lane closure times and minimizing traffic disruption—critical factors for inspection contracts with strict timeline requirements.
Unlike regional competitors, Anderson UnderBridge provides consistent service nationwide, ideal for engineering firms operating across multiple states. This capability is particularly valuable for firms with multistate DOT contracts.
From traffic control coordination to equipment delivery and certified operators, we provide comprehensive service packages that eliminate logistical challenges from your inspection projects.
With engineering firms increasingly opting for rentals over ownership, our extensive rental fleet helps accommodate your project schedules without the need for capital investment in equipment.

Articulated Boom Equipment
Approximately 15% of bridges with complex designs, such as truss structures or extensive cross members, require a unique approach and a different type of equipment. For these situations, Anderson UnderBridge offers articulated boom trucks. These versatile units provide the flexibility and maneuverability needed when other equipment solutions are not optimized for certain bridge structures or designs. Articulated boom equipment is:
- Ideal for bridges with significant vertical obstructions
- Capable of reaching between structural elements
- Perfect for high-wall applications requiring reach-over capabilities
- Available with industry-certified operators
Ideal for:
Suspension
