All oversize loads entering Bellevue, Washington must conform to the requirements set by the Washington Department of Transportation (WADOT) and the Bellevue Department of Transportation (BELDOT).

In general, any vehicle over 12 feet in width, 14 feet 0 inches in height, and within the super heavy weight class (over 290,447 lbs) should obtain an oversize load permit from the WADOT and potentially additional permits from BELDOT.

To navigate the complexities of Bellevue's infrastructure, it's crucial to plan routes that avoid sensitive areas like the Bellevue Bay and major construction zones along the Bellevue Commercial Zone area.

Washington law mandates escort vehicles for any load exceeding 16 feet in width or 14 feet 6 inches in height. When traveling through Bellevue, these requirements may be more stringent depending on the specific streets and neighborhoods traversed.

The Bellevue Department of Transportation requires a minimum of 30 hours advance notice to coordinate police escorts, which are mandatory for super-loads or when traveling through congested areas of Bellevue.

The Washington Department of Transportation manages the primary application process for oversize permits, with supplementary permits required from Bellevue Department of Transportation for transit through Bellevue limits.

Required documentation for Bellevue permits includes axle configuration diagrams, proof of insurance with appropriate coverage levels, and detailed transport plans. Engineering assessments may be required for loads exceeding standard weight thresholds on certain streets and bridges.

Bellevue has strict time-of-day restrictions for oversize loads, generally prohibiting movements during peak hours (7-8 am and 3-5 pm, Monday-Friday).

Seasonal restrictions apply during major events like the the Bellevue Heritage Tournament and the the Bellevue Heritage Show, which may impact routing and scheduling.

Certain neighborhoods, such as Downtown Bellevue and areas around Bellevue Hills, have restricted access for oversize loads. Alternative routes should be planned in advance to avoid these areas.

The base permit fee for an oversize load in Washington is $40, with additional fees for super heavy loads (over 200,000 lbs) ranging from $150 to $350 depending on the complexity of the move.

For movements within Bellevue, Bellevue Department of Transportation may charge additional fees for city-specific permits, which can range from $75 to $500 or more for particularly complex routes or those requiring extensive coordination with city agencies.
