Introduction
Applying for a Washington oversize permit is an important step when transporting loads that exceed the state's legal size or weight limits. Depending on your vehicle configuration and the weight of your load, the Washington State Department of Transportation (WSDOT) may require a bridge review before your oversize permit can be approved. This review helps determine whether bridges along your planned route can safely support your vehicle while protecting Washington's transportation infrastructure.
Understanding how a bridge review works before submitting your application can save valuable time and help prevent unnecessary delays. Preparing accurate vehicle information, selecting an appropriate route, and applying early all contribute to a smoother permitting process. Whether you're hauling construction equipment, agricultural machinery, or another type of oversize load, taking the time to prepare can help keep your shipment moving on schedule.
Understanding A WSDOT Bridge Review
A WSDOT bridge review is an engineering evaluation performed to determine whether a specific vehicle can safely travel across bridges located on the requested route. During the review, engineers examine how your vehicle's weight is distributed and evaluate whether individual bridges can safely handle the load.
The review considers several important factors, including gross vehicle weight, axle spacing, axle weights, vehicle configuration, and the route requested on the permit application. Each bridge along the proposed route may be evaluated differently depending on its design and current condition.
Although many oversize permit applications are processed without requiring additional engineering analysis, overweight loads and specialized hauling equipment are more likely to require a bridge review before a permit can be issued.
When A Bridge Review Is Required
Not every oversize load requires a bridge review. The need for one depends on the characteristics of the vehicle and the proposed route. Heavy construction equipment, cranes, industrial machinery, transformers, and other exceptionally heavy loads commonly require engineering review before travel is approved.
A bridge review may also be necessary when a vehicle has an uncommon axle configuration or unusually high axle weights. Even if a similar load has previously traveled through Washington, changes to the vehicle, route, or weight distribution could require a new evaluation.
Since bridge reviews require additional processing, trucking companies should avoid waiting until the last minute to apply. Allowing extra time helps reduce scheduling challenges if additional engineering analysis becomes necessary.
Information You Need Before Applying
Submitting complete and accurate information is one of the best ways to prepare for a WSDOT bridge review. Engineers rely on the information provided in the permit application to evaluate how your vehicle will interact with bridges along the requested route.
Before applying, gather the following information:
-
Vehicle and trailer details
-
Overall gross vehicle weight
-
Individual axle weights
-
Axle spacing measurements
-
Overall height, width, and length
-
Origin and destination
-
Proposed travel route
Review all measurements carefully before submitting your application. Even small errors in axle spacing or weight calculations may require corrections and extend the review process.
Keeping equipment specifications readily available can also make future permit applications faster and easier.
How Bridge Reviews Affect Your Route
One of the primary purposes of a bridge review is determining whether your proposed route can safely accommodate your vehicle. If engineers determine that one or more bridges cannot safely support the load, WSDOT may recommend an alternate route.
In some situations, permit conditions may include special instructions for crossing specific bridges. These instructions could require reduced speeds, lane restrictions, or other operational requirements designed to protect public infrastructure.
Although route adjustments may seem inconvenient, they help ensure both roadway safety and the long-term preservation of Washington's bridge system.
Understanding that route modifications are sometimes part of the review process allows trucking companies to build additional flexibility into their transportation schedules.
Common Reasons Bridge Reviews Take Longer
While many bridge reviews are completed efficiently, certain circumstances can increase processing time. Incomplete applications are one of the most common reasons for delays. Missing axle weights, incorrect measurements, or incomplete route information often require follow-up communication before engineers can continue their evaluation.
Route complexity is another factor. Trips involving numerous bridges or heavily traveled corridors may require more detailed analysis than shorter or less complicated routes.
Seasonal road construction, temporary bridge restrictions, emergency repairs, and highway improvement projects can also influence permit routing. Engineers must consider these changing conditions when reviewing permit requests.
Applying early and providing complete information gives WSDOT more time to perform the necessary engineering review and reduces the likelihood of avoidable delays.
Planning Ahead For A Successful Bridge Review
Preparation begins well before the permit application is submitted. Trucking companies should verify that all vehicle specifications are current and ensure the proposed route reflects actual travel plans.
If equipment has recently been modified or a different trailer will be used, measurements should be updated before applying. Accurate information allows engineers to complete their calculations without requesting additional corrections.
It is also helpful to communicate with dispatchers, drivers, and logistics coordinators during the planning process. Confirming travel dates, pickup schedules, and delivery deadlines before submitting the application provides more flexibility if routing adjustments become necessary.
Many carriers also maintain detailed records of their equipment specifications so permit applications can be completed more efficiently throughout the year. Organized records reduce the chance of entering outdated information and help simplify future applications.
Tips To Avoid Delays During The Review Process
Although every permit application is different, several best practices can help improve the overall process.
-
Verify all axle weights before applying.
-
Double-check axle spacing measurements.
-
Confirm the proposed travel route.
-
Submit complete vehicle information.
-
Apply well before the planned travel date.
-
Respond promptly if additional information is requested.
-
Review the entire application before submission.
Careful preparation helps reduce unnecessary processing delays and allows bridge reviews to move forward as efficiently as possible.

FAQ
What is a WSDOT bridge review?
A WSDOT bridge review is an engineering evaluation that determines whether bridges along a proposed route can safely support an oversize or overweight vehicle.
Does every Washington oversize permit require a bridge review?
No. Only certain vehicles, weights, and axle configurations require a bridge review before an oversize permit can be approved.
Can WSDOT change my travel route?
Yes. If engineers determine that your proposed route is unsuitable, WSDOT may require an alternate route or include special travel instructions on the permit.
How can I help speed up the bridge review process?
Submitting accurate vehicle information, complete axle measurements, and applying well before your planned travel date can help reduce delays.
What happens if my vehicle information changes after I submit my application?
If your vehicle configuration, axle weights, or dimensions change, you should update your permit application before traveling to ensure the information remains accurate.
