PREFABRICATED MODULAR VEHICULAR BRIDGES
ACCELERATED CONSTRUCTION – MEETS STATE AND LOCAL REQUIREMENTS
TrueNorth Steel
MODULAR VEHICULAR BRIDGES
TrueNorth Steel vehicular bridges are built on design flexibility, cost efficiency, and shortened project time.
By combining the design flexibility to meet specific application requirements, with the cost efficiencies of reduced installation time, we are able to provide low-cost durable, pre-fabricated, high-quality modular bridge designs that meet AASHTO, state and local bridge design requirements.
Your prefabricated bridge modules are shipped directly to the jobsite so they can be quickly and easily assembled and installed by contractors or county crews, resulting in minimal road closure times.
Our prefabricated steel bridges can accommodate asphalt, concrete, gravel or treated timber driving surfaces. We offer prefabricated steel back walls, pre-engineered SuperSill® abutments, guiderail systems and concrete abutment design services ensuring your bridge design is fully integrated with your project.

Why TrueNorth Steel
EXPERIENCE. COMMITMENT. QUALITY.
Modular Bridges
TrueNorth Steel prefabricated vehicle bridges feature simple modular construction but deliver big on aesthetics and quality details. We pre-manufacture components in our AISC-certified facilities, where we use only the highest quality materials and welding procedures. This process shortens lengthy production timelines while ensuring you get easy and fast, bolt-together installation at a low cost.
Engineering
TrueNorth Steel has the engineering expertise to provide stamped engineering design drawings for our prefabricated modular vehicular bridges, as well as for bridge abutments.
Our engineers are certified P.E. licensed, and registered in all 50 states and they’re familiar with state and local design code requirements. We are ready to support your project wherever you are located.

Additional Engineering Services:
Bridge Load Rating– Increasingly, state departments of transportation “DOT” are requiring load ratings for new vehicular bridges and bridge replacements if they are connected to the national highway system “NHS”. Depending upon the state DOT, the process of load rating the bridge design itself (prior to construction) can be very simple or it can require specialized software. In either case, TrueNorth Steel can help.
If you have questions about the load rating requirement, contact us at Bridge@TrueNorthSteel.com or call us at 406-532-7103

Typical Modular Vehicular Bridge
Accelerate Bridge Construction
Simplify installation with modular construction. Typical pre-manufactured bridge projects are finished within one to three days, thus reducing installed cost.
- Download TrueNorth Steel vehicular installation guide by clicking here.
- Up to 50’-0,” span individual bridge modules can be set with one or two excavators- no need to rent a crane.
- When a crane is required, the crane service time will be minimal given the modular construction.
- If soil conditions are conducive to a perched-style spread footing abutment, our pre-engineered/prefabricated SuperSill® can be set with an excavator and filled with concrete or shipped to the jobsite pre-filled.
- Bridge guardrail systems are pre-installed on bridge modules.
- Bolt-on back walls simplify construction of our pre-made bridges so you can quickly build your road approaches and install surfacing on the heavy duty galvanized corrugated deck
