All oversize loads entering the City of High Bridge, in Snohomish County, must conform to the requirements set by the Washington Department of Transportation (WSDOT) and High Bridge municipal codes.

In general, any vehicle exceeding 8 feet 6 inches in width, 14 feet in height, or with a gross vehicle weight exceeding 80,000 lbs should obtain an oversize load permit from the High Bridge Public Works Department. Note that these limits apply to travel on city streets; state highways within High Bridge may have different restrictions.

High Bridge experiences occasional flooding along the Stillaguamish River. During flood events, certain routes may be closed or have weight restrictions. Check with the Public Works Department for current conditions before planning your route.

Escort vehicles are typically required in High Bridge when loads exceed 12 feet in width, 14 feet 6 inches in height, or 100 feet in length. Specific requirements depend on the route and potential obstructions.

For loads exceeding 14 feet in width or 16 feet in height, a Washington State Patrol (WSP) escort is generally required, in addition to private escorts. Contact the WSP Commercial Vehicle Enforcement Section (CVE) for scheduling and fee information. Expect to pay around $75/hour for WSP escort services, with a minimum of 4 hours.

Required documentation includes a detailed route plan, vehicle and load specifications, and proof of insurance. For especially large or heavy loads, a structural analysis of bridges along the route may be required. The City Engineer will review this analysis.

Time-of-day restrictions are in effect in High Bridge. Oversize loads are typically not permitted to travel during peak commute hours (7:00 AM - 9:00 AM and 4:00 PM - 6:00 PM) on weekdays, especially on Highway 530.

Seasonal weight restrictions may be imposed on certain roads during the winter months to protect pavement from damage due to freeze-thaw cycles. Check with the Public Works Department for current restrictions.

Avoid residential streets whenever possible. Travel through the older section of High Bridge (near the river) requires extra caution due to narrow streets and overhead utilities. Specific routes through this area must be pre-approved.

The base permit fee for oversize loads in High Bridge is $25.00. Additional charges may apply depending on the size and weight of the load, the length of the route, and the need for escorts or traffic control.

Fees increase incrementally based on the gross vehicle weight (GVW). Loads exceeding 100,000 lbs GVW will incur higher fees. Bridge analysis fees are separate and depend on the complexity of the analysis.
