Heavy haul permitting software that holds the load once and files it across every state
Heavy haul oversize load permitting is the process of getting state by state authority to move freight that exceeds legal size or weight limits. Federal Interstate limits under 23 CFR Part 658 are 80,000 pounds gross, 20,000 pounds on a single axle and 34,000 pounds on a tandem, with width at 102 inches. Neurobird holds the load dimensions and axle configuration once, then keeps every state application, escort rule and curfew aligned to the same travel dates.
Neurobird Heavy Haul Oversize Load Permitting in short
- Hold the load dimensions, axle spacings and weights once and apply them to every state
- Track permit status, validity windows and expiry across all states on a single move
- Keep escort, curfew and holiday restrictions attached to the route rather than to memory
- 80,000 Federal maximum gross vehicle weight on the Interstate system, with 20,000 pounds on a single axle and 34,000 on a tandem, beyond which a permit is required. Electronic Code of Federal Regulations, 23 CFR Part 658
- 102 Federal width limit in inches on the National Network, which is why almost every wide load is a permitted load. Federal Highway Administration, truck size and weight laws
- Pricing runs 160 to 600 US dollars per month across 3 tiers. Early access is free.
What heavy haul carriers and permit services actually deal with
Why it stays broken
Permitting is a data entry problem wearing a compliance costume. The same 20 facts about a load go into 4 or 5 state systems by hand, and nothing holds the move as a single thing with 1 set of dates.
A bridge analysis that returns 5 days late can invalidate permits in 3 states at once.
Federal weight standards apply to commercial vehicle operations only on the Interstate Highway System, which consists of approximately 50,000 miles of limited access, divided highways that span the Nation.

Model the load and the route as one record. Every state application then draws from it, and a date change is one change rather than four.
- 1Hold the load dimensions, axle spacings and weights once and apply them to every state
- 2Track permit status, validity windows and expiry across all states on a single move
- 3Keep escort, curfew and holiday restrictions attached to the route rather than to memory
- 4Show the axle configuration against federal and state weight limits before a permit is even filed
What changes with Neurobird Heavy Haul Oversize Load Permitting?
The same work, read left to right: how it runs today, and how it runs once the record is in one place.
| Today | With Neurobird Heavy Haul Oversize Load Permitting |
|---|---|
| Every state wants the same 20 facts in a different form, and the coordinator retypes them 4 times per move | Hold the load dimensions, axle spacings and weights once and apply them to every state |
| A bridge analysis comes back late, the permit dates no longer line up, and 3 states have to be reapplied for | Track permit status, validity windows and expiry across all states on a single move |
| Escort, curfew and holiday restrictions live in a coordinator's memory, so a load leaves and stops at a county line | Keep escort, curfew and holiday restrictions attached to the route rather than to memory |
Who is this for?
Same move, three different exposures.
You pull your own permits
Permitting is unpaid time between loads. You need the same facts to fill 4 applications instead of 1 typed 4 times.
You run a permit desk
Two coordinators cover dozens of moves. You need one board showing what is filed, what is pending and what expires this week.
You file for other carriers
Your product is accuracy and turnaround. You need client portfolios and a record of every condition attached to every permit.
How does Neurobird Heavy Haul Oversize Load Permitting work?
Describe the load once
Dimensions, axle spacings, weights and configuration are entered once and checked against federal and state limits before you apply.
File and track per state
Each state application carries its own status, fee, validity window and conditions, all pointing at the same load.
Hold the route conditions
Escorts, curfews, holiday bans and restricted structures attach to the route, so the driver leaves with the restrictions rather than a phone call.

Heavy haul oversize load permitting software questions, answered
Key terms
- What is oversize and overweight permitting?
- Oversize and overweight permitting is the process of getting state by state authority to move a load that exceeds legal size or weight limits. On the Interstate system federal limits under 23 CFR Part 658 sit at 80,000 pounds gross, 20,000 pounds on a single axle and 34,000 pounds on a tandem, with width at 102 inches, and anything beyond that needs a permit from each state crossed.
- What is the federal bridge formula?
- A formula that limits weight based on axle spacing and the number of axles, so a heavier load may be legal if it is spread over a longer wheelbase. It is why the axle configuration, not just gross weight, decides whether a route is even worth applying for.
Why does one move need so many permits?
Because permitting authority is state by state, and often county and city as well. A 612 mile move across 4 states is 4 separate applications with 4 fee schedules, 4 escort rules and 4 sets of curfew and holiday restrictions, all of which have to agree on the same travel dates.
Does this replace the state permit portals?
No. States keep their portals and their fees. This holds the load once, keeps every application aligned to the same dimensions and dates, and warns you when a permit window and a bridge analysis have drifted apart.
Why we are building this
Heavy haul is precise work at the trailer and improvised work at the desk. The rigging is engineered. The permitting is retyping.
The whole load is about 20 numbers. Those 20 numbers get entered into 4 or 5 systems by hand, and every date change means doing it again.
We would rather build this with permit coordinators than guess. Tell us how a move gets filed at your desk, and where we have got it wrong.
Where the requirement comes from
Federal limits and the state practice that sits on top of them.
- 23 CFR Part 658, truck size and weight Federal weight and width limits on the Interstate and National Network, the baseline every permit exceeds.
- FHWA compilation of state truck size and weight laws State by state limits and permit practice, the reference for why a route changes at the line.
- FHWA bridge formula weights How allowable weight relates to axle spacing and number of axles.
- FHWA oversize and overweight permit practice Federal reporting on how states administer oversize and overweight permits.
