Arlington, Washington regulations require all heavy haul operations to comply with the Washington Department of Transportation (WADOT) guidelines as well as local ordinances administered by the Arlington Department of Transportation (ARLDOT).

Heavy haul permits are required for any load exceeding 13 feet in width, 13 feet 0 inches in height, or 290,839 lbs in gross vehicle weight. These dimensions are strictly enforced throughout Arlington, particularly in high-traffic areas.

Special consideration must be given to route planning to avoid Arlington Bridge and the vicinity of Arlington Municipal Complex, which have infrastructure limitations or heavy pedestrian traffic that may impede oversized loads.

In Arlington, Washington, loads wider than 17 feet or taller than 15 feet 6 inches must be accompanied by certified escort vehicles. Additional escorts may be required based on the specific route and time of travel through urban centers.

Arlington regulations state that police escorts must be arranged at least 32 hours before transport for loads that will impact major thoroughfares or require temporary traffic control measures.

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

Required documentation for Arlington 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.

Arlington has strict time-of-day restrictions for oversize loads, generally prohibiting movements during peak hours (7-9 am and 4-6 pm, Monday-Friday).

Seasonal restrictions apply during major events like the the Arlington Holiday Exhibition and the the Arlington Historical Celebration, which may impact routing and scheduling.

Certain neighborhoods, such as Downtown Arlington and areas around Arlington Shopping District, 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 Arlington, Arlington 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.
