Transporting oversized or overweight cargo involves more than just having the right truck, it requires detailed planning and precise coordination, plus expert knowledge of state and federal laws. This type of cargo often involves unique equipment, restrictive travel hours, and strict documentation requirements. One missed step can delay your cargo and cost your business thousands of dollars.

At Century Express Virginia, we oversee all of this for our customers. Our team handles the full scope of heavy cargo permitting and logistics. We make sure your shipment meets every legal requirement from pickup to delivery.

Whenever you need to ship heavy freight, having a trusted carrier on your side means fewer delays and fewer surprises. That’s what Century Express Virginia delivers.

This blog will walk you through what qualifies as overweight cargo, the challenges of interstate permitting, and how our turnkey approach helps you move oversized freight with confidence.

What Is Considered ‘Overweight’ Cargo?

Overweight or overdimensional cargo is any shipment that exceeds the standard size or weight limits for highway travel. Federal guidelines set these limits, but each state can apply its own specific rules. As a result, you need an understanding of both national and local thresholds.

General Legal Limits for Highway Travel:

• Width: 8 feet 6 inches
• Height: 13 feet 6 inches
• Length: 48–53 feet for trailers (varies by state)
• Weight: 80,000 pounds GVW (gross vehicle weight)

Anything exceeding these dimensions requires a special permit. In many cases, you might also need an escort vehicle, signage, and route planning.

Examples of Overweight or Oversized Freight:

• Construction machinery (excavators, bulldozers)
• Wind turbine blades or tower components
• Industrial tanks or boilers
• Large generators and transformers
• Precast concrete sections
• Agricultural equipment (combines, planters)

These cargo types often make up part of time-sensitive construction, energy, or infrastructure projects. A delay in delivery can hold up an entire job site, costing thousands of dollars in lost productivity. In some industries, oversized freight also needs to be delivered during specific hours to meet site restrictions or unloading availability.

It’s not just about physical size. Shipment weight, balance, and trailer compatibility all factor into identifying a load as “overweight.” Understanding how to match cargo with compliant equipment holds as much importance as the permits themselves.

The Challenge of Multi-State Permitting

Obtaining permits for a single state has enough complications, but crossing multiple states with an oversized load creates a whole new level of complexity.

Each state has its own set of:

• Size and weight thresholds for requiring permits
• Travel time restrictions (night, weekend, or holiday movement)
• Escort vehicle requirements (spacing, signage, and certifications)
• Road, bridge, and tunnel limitations based on infrastructure capacity
• Seasonal restrictions or weather-related closures

Even when two neighboring states have similar rules, the permit application process may differ entirely. Some states use electronic portals, while others require phone calls or faxed documentation. Processing times also vary. Some permits get issued instantly, while others can take days.

What Happens If You’re Not Fully Compliant?

• Fines and citations. Non-compliance can result in immediate penalties.
• Detainment. Your load may be stopped at a checkpoint or weigh station.
• Offloading. In serious cases, law enforcement may require you to offload or reroute your cargo.
• Loss of customer trust. Delays and penalties can reflect poorly on your service reliability.

It takes significant time and effort to manage these permits. Shippers or logistics teams that don’t regularly handle oversized freight often overlook a small requirement, such as applying for a weekend travel exception or checking bridge weight limits along a specific route. Unfortunately, these oversights can lead to stopped loads and missed delivery windows.

That’s why many companies turn to specialists like Century Express Virginia to take the lead.

Our Team’s Permitting Expertise

Our permitting team has worked directly with DOT offices, transportation departments, and escort service providers across the country for nearly 20 years. We know which states process quickly, which require extra documentation, and how to fast-track approvals when needed.

We also keep up with annual regulatory changes, ensuring every route and permit follows the latest state and federal guidelines. This plays an important role during seasonal changes, construction detours, or natural disaster re-routings that may impact safe travel for oversized loads.

Avoiding Common Mistakes with Heavy Cargo Transport

Many shippers underestimate what goes into moving oversized loads. Some of the most common mistakes we help clients avoid are:

• Assuming permits are optional
• Overlooking state holidays and time-of-day restrictions
• Failing to verify bridge weight limits
• Delaying permit applications

Each one of these oversights can impact delivery contracts, project timelines, and client satisfaction. In many cases, we’ve helped clients recover from mistakes made by less experienced carriers, rerouting delayed cargo due to improper permitting or non-compliant equipment.

When you work with Century Express Virginia from the start, you avoid these risks altogether.
