Bridge Analysis for Oversize & Superload Permits
Bridge analysis determines whether a bridge can safely support the weight and axle configuration of your vehicle. Many states require this review before issuing permits for heavy or superloads.
Bridge analysis determines whether a bridge can safely support the weight and axle configuration of your vehicle. Many states require this review before issuing permits for heavy or superloads.
What is Bridge Analysis?
Bridge analysis is an engineering review used to evaluate how your vehicle's weight is distributed across each bridge on the approved route. The goal is to protect infrastructure while ensuring the load can travel safely.
When is Bridge Analysis Required?
Bridge analysis may be required when:
Your gross vehicle weight is exceptionally high.
Your axle configuration places excessive stress on bridge structures.
Your load qualifies as a superload.
A state engineering office requests additional review.
What Information is Needed?
Vehicle configuration
Overall gross weight
Axle weights
Axle spacing
Overall dimensions
Proposed route
What Happens During the Review?
Engineers evaluate your vehicle configuration against every bridge on the proposed route. If a bridge cannot safely support the load, an alternate route or additional restrictions may be required before the permit is approved.
Why It Matters
Bridge analysis helps prevent permit delays, protects public infrastructure, reduces routing changes, and ensures compliance with state engineering requirements.
Quick Facts
Performed By:
State Bridge Engineers or Engineering Division
Most Common For:
Heavy haul and superload movements
Review Time:
Varies by state and route complexity
Possible Outcome:
Approved route, alternate route, or additional travel restrictions
Permit Pro Tip
Many bridge analysis delays are caused by incorrect axle spacing.
Even a small measurement error can require the engineering review to be restarted.
Always verify axle spacing before submitting your permit request.
