Nationwide Heavy Haul Permits

Navigating the complex regulatory landscape of oversize and overweight transport. We secure permits, coordinate police escorts, and engineer safe routes for the nation's heaviest cargos.

Overweight Load Permits

Rapid acquisition of single-trip and annual overweight permits for 50 states. We handle state, county, and municipal jurisdictions.

Route Surveys & FEA

Physical route surveys, bridge engineering analysis (FEA), and swept path modeling for superloads exceeding 200,000 lbs.

Civil Escort Coordination

Direct coordination with State Police, Utility Companies, and DOT officials for bucket truck assistance and police escorts.

Superload Engineering

Detailed axle weight distribution analysis and schematic drafting to meet state bridge formulas (Federal Bridge Formula B).

Understanding Overweight Load Permits

Every state has unique regulations for oversize and overweight transport. While federal laws standardize weight limits on the Interstate system (80,000 lbs gross), anything exceeding this requires a state-issued permit.

When is a Route Survey Required?

For superloads (typically exceeding 16' high or 200,000 lbs), specialized heavy haul trucking companies must perform a physical route survey. This involves a pole car driving the exact route to measure overhead obstructions and bridge engineering analysis to ensure structural integrity.

Multi-State Permitting

The challenge of heavy haul logistics is coordinating permits across state lines. A load legal in Texas might require a superload permit in Louisiana. Everdauer manages this entire "permit matrix" to ensure seamless cross-country transport without delays at the scales.

Permit Turnaround Times

Routine Oversize 2-4 Hours
Superload (Analysis) 3-10 Days
Annual Permits 24 Hours

*Typical turnaround times. Complex route surveys or utility moves may take longer.

Permit & Regulations FAQs

Answers about OSOW permits and route survey requirements.

OSOW stands for Oversize/Overweight, referring to loads that exceed standard legal dimensions or weight limits for highway travel. In the U.S., standard legal limits are typically 8.5 feet wide, 13.5 feet tall, 48-53 feet long, and 80,000 pounds gross vehicle weight. Any load exceeding these limits requires OSOW permits.
Standard OSOW permits can often be obtained within 24-48 hours. However, superload permits requiring bridge analyses may take 1-2 weeks. Multi-state permits require coordination with each state's DOT. Our expedited permit service can often reduce these timeframes for urgent shipments.
A superload is an extremely heavy or oversized load that exceeds standard oversize permit limits. Definitions vary by state but generally include loads over 16 feet wide, 16 feet tall, 150 feet long, or 200,000+ pounds. Superloads require extensive planning including bridge analyses, route surveys, utility coordination, and often police escorts.
Yes, oversize loads can travel on interstate highways with proper permits. However, some interstates have restrictions on load dimensions, travel times (often requiring night moves for extremely wide loads), and may prohibit travel during peak hours, holidays, or adverse weather. Our routing team plans optimal routes that comply with all restrictions.
Most states restrict oversize load travel to daylight hours (30 minutes before sunrise to 30 minutes after sunset). Many states prohibit travel on holidays, weekends, and during rush hours. Extremely wide loads may be required to travel at night when traffic is minimal. We handle all scheduling to comply with these restrictions.
