Fast, reliable & cost effective Equipment Transport

Getting your loads where they need to go starts with proper planning. Skipping steps in structural assessments or approved pathways can lead to costly delays and fines. Compliance isn’t just paperwork—it keeps everyone safe and projects on track.

In Washington State, the WSBIM Manual (M 36-64.15) is your go-to guide. It outlines everything from load ratings to permit approvals. Ignoring these rules risks road closures or even legal trouble.

New to the process? Don’t worry. This guide breaks it down step by step, so you can focus on the road ahead—safely and efficiently.

Why Bridge Inspections on Permit Routes Matter

Safety hinges on regular, detailed reviews. Without proper checks, even sturdy infrastructure can fail. The 1967 Silver Bridge collapse—killing 46 people—shows why evaluations aren’t just paperwork.

The Role of Evaluations in Safety

Assessments ensure bridges handle weight limits. They spot cracks, corrosion, or wear before disasters strike. Compliance with the WSBIM Manual keeps routes open and drivers safe.

Risks of Skipping Checks

King County holds truckers liable for unpermitted loads. Damage claims can exceed $25,000. Load rating gaps? Instant permit denials. Right now, 10 bridges there have strict limits.

NBIS rules require posting deficient structures. Ignoring them risks fines, delays, or worse—catastrophe. Your route’s safety depends on these checks.

Understanding Permit Routes and Their Requirements

Federal and state rules shape how you move oversized loads. Permit routes combine these regulations to create safe pathways for heavy vehicles. They’re not just any roads—they’re approved after rigorous checks.

What Defines a Permit Route?

These routes include bridges rated for specific weights. For example, AASHTO Type 3 trucks (like 3S2 or 3-3) are used to test standard load ratings. Axle spacing matters too—tighter gaps spread weight better.

Federal law caps loads at 80,000 lbs, but states can set stricter rules. Washington’s WSBIM Manual defines “overlegal” loads as those exceeding size or weight limits, even if structurally safe.

Legal vs. Posted Load Limits

Legal load limits follow national standards. Posted limits reflect a bridge’s actual condition. If a sign says 40 tons, that’s your max—no matter what federal rules allow.

WSDOT distinguishes “overweight” (exceeding capacity) from “overlegal” (within capacity but oversized). Always check both before hauling.

• Federal rule: 80k lbs gross weight
• State variations: Washington allows 105,500 lbs with permits
• Axle spacing: 8–12 feet reduces bridge stress

Key Components of a Bridge Inspection

Behind every safe crossing lies a meticulous evaluation process. Experts follow strict protocols to ensure structures can handle daily wear—and your heavy loads. Here’s what they examine.

Structural Integrity Checks

The WSBIM Manual outlines a 9-step process for reviewing critical components. Inspectors look for:

• Cracks in beams or joints
• Corrosion from weather or salt
• Loose bolts or worn bearings

Roman Peralta (360-570-2557) leads preservation efforts, prioritizing repairs based on these findings.

Load Rating Evaluations

Not all bridges handle the same weight. Mohamad Al-Salman (360-570-2567) verifies ratings using AASHTO formulas. Key factors include:

• Axle spacing (8–12 feet reduces stress)
• Material fatigue over time
• Historical traffic patterns

Chapter 5 of the WSBIM details how ratings adjust for aging infrastructure.

Scour and Damage Assessments

Water erodes foundations silently. King County’s dive team measures six scour indicators:

1. Riverbed depth changes
2. Exposed pilings
3. Sediment buildup

Damage assessments (Chapter 6) guide repairs—like patching spalls or replacing corroded rebar.

Remember: A single unchecked flaw can escalate into a crisis. Regular reviews keep routes open and freight moving.

Navigating Bridge Inspections on Permit Routes: A Step-by-Step Guide

Planning your heavy haul starts with knowing exactly what’s on your path. Follow these steps to ensure compliance and avoid delays.

Step 1: Identify the Bridges on Your Route

First, pinpoint every structure you’ll cross. Washington’s WSDOT Bridge List (M 23-09) maps them clearly. Check for updates—some routes change due to repairs or seasonal limits.

Pro tip: Download King County’s Restricted Bridges list (573KB) for real-time closures. Winter weight limits often apply, so verify dates.

Step 2: Review Inspection and Load Rating Reports

Pull the latest inspection reports three ways:

• Online portals like WSDOT’s Bridge Data System
• Email requests to regional offices
• Phone calls to bridge engineers (e.g., 360-570-2567)

Cross-check findings with WSBIM Chapter 3 codes. Look for red flags like corrosion or low load rating reports.

Step 3: Check for Restrictions or Special Conditions

Even permitted loads face surprises. Watch for:

• Time-of-day bans (e.g., rush hour)
• Escort vehicle requirements
• Detours for ongoing repairs

Restrictions vary by county. Always confirm with local DOT offices before departure.

How to Access Bridge Inspection Manuals and Resources

State manuals hold the keys to safe and compliant hauling. Federal and state standards are compiled in documents like Washington’s WSBIM Manual (M 36-64.15), a 20.1MB PDF available for direct download. These resources clarify weight limits, repair protocols, and load ratings.

Finding and Using the WSBIM Manual

Download the latest version of the WSBIM from official DOT portals. Key chapters include:

• Chapter 3: Inspection codes for cracks or corrosion
• Chapter 5: Load rating formulas (AASHTO Type 3 examples)
• Chapter 6: Scour and damage assessment criteria

Revision packages update the manual quarterly. Subscribe to WSDOT’s alerts to track changes.

“Always cross-reference the manual’s load tables with current permit applications. Outdated data risks route rejections.”

Decoding Technical Details

The manual’s technical details can be daunting. Use this table to interpret common Chapter 3 codes:

Code	Meaning	Action Required
3C	Moderate cracking	Monitor annually
4R	Severe rebar corrosion	Immediate repair
2S	Minor scour	Reinforce foundation

For complex calculations, contact the Load Rating Team (360-570-2567). They’ll walk you through examples like this:

1. Input axle spacing (e.g., 10 feet)
2. Multiply by material fatigue factor (0.85 for steel)
3. Compare to bridge’s posted limit

Pro tip: Bookmark the WSBIM’s glossary—it defines terms like “overlegal” versus “overweight.”

Preparing for Your Bridge Inspection

Efficient preparation ensures smooth approvals and avoids last-minute delays. Whether you’re a first-time applicant or a seasoned hauler, having a clear plan saves time and keeps your project moving.

Gathering Necessary Documentation

King County requires seven key documents for permit applications. Submit these via email to permits.roads@kingcounty.gov to ensure compliance:

Document	Purpose
Load Calculation Sheets	Proves weight distribution meets limits
Route Map	Shows exact bridges and roads
Vehicle Specifications	Details axle spacing and dimensions
Insurance Certificate	Covers potential damages

Processing times vary:

• 1-day turnaround: For standard loads with complete paperwork.
• 3-day review: Needed for oversized or complex routes.

Coordinating with Inspection Teams

Call Andrew Easley (206-423-8907) weekdays from 8 AM–3 PM for quick responses. For after-hours emergencies, dial the WSDOT hotline and cite “structural urgency.”

Follow up with engineers using this email template:

“Subject: Follow-Up on Permit #12345
Hi [Engineer’s Name],
Could you confirm receipt of my application? Attached are the revised load sheets. Let me know if you need additional details.
Best, [Your Name]”

Coordination with inspection teams reduces delays. Keep records of all communications for reference.

The Role of Load Ratings in Permit Routes

Your truck’s weight distribution directly affects which routes you can take. Load ratings determine whether bridges can handle your cargo safely. These calculations follow strict standards to prevent structural damage.

How Load Ratings Are Determined

The AASHTO Standard Specifications Division 6 governs rating methods. Engineers like Mohamad Al-Salman (360-570-2567) use these formulas:

• Measure maximum stress points on bridge beams
• Factor in material age and wear
• Calculate weight distribution per axle

Five factors trigger new ratings automatically:

1. Major repairs (e.g., beam replacements)
2. Flood damage to foundations
3. Increased traffic volume
4. Material corrosion exceeding 15%
5. Changes to adjacent roadways

Impact of Axle Configurations on Permits

A 6-inch spacing change can alter your eligibility. Case study: A King County hauler reduced spacing from 12 to 11.5 feet. This dropped their permit approval by 8,000 lbs.

Visual spacing guide:

Axle Distance	Weight Capacity
8 feet	+12% vs. standard
10 feet	Baseline rating
12 feet	-9% for long spans

“Always verify configurations against our pre-approved database. Even 3-inch differences matter.”

Access the database via permits.roads@kingcounty.gov with subject line “Axle Config Request.” Include your vehicle VIN for fastest results.

Common Bridge Inspection Challenges and How to Overcome Them

Even with careful planning, unexpected hurdles can slow down your haul. In King County alone, 185 structures undergo inspections every two years—but gaps in data or access can still create roadblocks. Knowing how to tackle these challenges keeps your shipments moving smoothly.

When Bridges Have Restrictions

Ten key structures in King County have strict limits. If your route includes them, try these solutions:

• Alternative crossings: Use WSDOT’s interactive map to find nearby approved paths.
• Split loads: Reduce weight by making multiple trips if possible.
• Expedited reviews: Contact Colt Tatum (707-227-8067) for urgent assessments.

For bridges marked “no overlegal loads,” exceptions are rare. Always check the latest postings before finalizing plans.

Missing or Outdated Inspection Reports

Old data can derail permits. If reports are incomplete:

1. Submit a records request via WSDOT’s online portal.
2. Attach this note to your application: “Pending current inspection data—per WSBIM 3.2.5.”
3. Challenge outdated ratings by emailing bridge.preservation@wsdot.wa.gov with evidence of repairs.

“Always document gaps in writing. Verbal requests won’t protect you if issues arise later.”

Keep this emergency list handy:

Pre-Approval for Frequent Overlegal Loads

Frequent haulers can skip the paperwork hassle with streamlined pre-approval options. King County offers six-month permits for carriers with verified configurations. This time-saving solution cuts repeat applications by 80%.

Benefits of Pre-Approval

Pre-approved permits reduce delays and costs. Here’s how:

• Cost savings: Pay once for six months instead of per trip (see table below).
• Faster processing: Pre-approved loads get priority review—often same-day.
• Automatic renewals: Compliant carriers avoid requalification.

Permit Type	Cost	Processing Time
Single-Use	$75 per trip	1–3 days
Pre-Approved	$300 flat fee	4 hours

How to Qualify and Apply

Meet these qualifications to start the process:

1. Submit 10+ compliant permits in the past year.
2. Use identical axle configurations for all loads.
3. Maintain a clean damage record (no violations).

Email Mohamad Al-Salman (mohamad.al-salman@wsdot.wa.gov) with subject line “Pre-Approval Request.” Attach:

• Vehicle specs (VIN, axle spacing)
• Previous permit numbers
• Insurance proof

“Pre-approved carriers see 63% faster processing. It’s our way of rewarding reliability.”

Understanding Bridge Inspection Reports

Decoding inspection reports helps you stay compliant and avoid costly mistakes. These documents contain critical details about structural conditions, load ratings, and safety concerns. Mastering their key sections ensures your loads meet all requirements.

What to Look for in Every Report

The WSBIM Chapter 3 outlines standard components. Focus on these areas:

• Condition ratings: NBIS uses a 0-9 scale (9 = excellent, 0 = failed)
• Crack measurements exceeding 0.25 inches
• Foundation scour depth changes

Example: A report showing “Rating 4” for deck condition means moderate deterioration exists. Cross-reference this with WSBIM Chapter 4 element lists for repair priorities.

Red Flags Requiring Immediate Action

Seven items demand urgent attention:

1. Corrosion affecting >15% of rebar
2. Beam deflection exceeding 1/800 of span length
3. Missing or damaged bearing pads

“Always verify report dates. Assessments older than 24 months may not reflect current conditions.”

Getting Clarifications on Complex Findings

Contact Roman Peralta’s team (360-570-2557) for help with:

• Conflicting data between reports
• Unclear repair recommendations
• Historical comparison requests

Email them the report ID and specific questions for fastest response. Include photos if you’ve observed new damage.

Report Section	Your Action
Load Rating Calculations	Compare with your vehicle specs
Scour Vulnerability	Check recent weather events
Element Conditions	Note any “4” or lower ratings

State vs. County Bridge Inspection Standards

Understanding the gap between state and county rules prevents costly oversights. Washington’s WSDOT oversees 3,200 structures, while King County manages 185. Their differences in protocols can trip up even experienced haulers.

Differences in Requirements

State and county teams prioritize different risks. For example, WSDOT focuses on seismic retrofits, while King County tracks localized scour damage. This table breaks down key contrasts:

Criteria	WSDOT (State)	King County
Inspection Frequency	Every 24 months	Every 12 months
Load Rating Method	AASHTO LRFR	Modified state formulas
Emergency Contacts	360-705-7200	206-477-6531

How to Ensure Compliance With Both

Dual-permit scenarios require extra steps. For the I-90 floating bridge, haulers must:

• Submit applications to both WSDOT and King County.
• Attach separate load calculations for each agency.
• Allow 48 extra hours for joint reviews.

“Always check funding sources. Federally backed bridges follow stricter timelines than county-maintained ones.”

For complex routes, email bridge.coordination@wsdot.wa.gov with your plan. They’ll flag overlaps upfront.

Best Practices for Maintaining Compliance

Staying ahead of regulations keeps your operations smooth and penalty-free. The WSDOT Bridge List (M 23-09) updates quarterly—missing these changes risks unexpected closures. Here’s how to stay sharp.
