All oversize loads entering Dixon, Illinois must conform to the requirements set by the Illinois Department of Transportation (ILDOT) and the Dixon Department of Transportation (DIXDOT).

In general, any vehicle over 12 feet in width, 16 feet 0 inches in height, and within the super heavy weight class (over 215,707 lbs) should obtain an oversize load permit from the ILDOT and potentially additional permits from DIXDOT.

To navigate the complexities of Dixon's infrastructure, it's crucial to plan routes that avoid sensitive areas like Dixon University and major construction zones along the Dixon Valley area.

Illinois law mandates escort vehicles for any load exceeding 17 feet in width or 15 feet 6 inches in height. When traveling through Dixon, these requirements may be more stringent depending on the specific streets and neighborhoods traversed.

The Dixon 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 Dixon.

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

Required documentation for Dixon 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.

Dixon 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 Dixon Heritage Games and the the Dixon Summer Marathon, which may impact routing and scheduling.

Certain neighborhoods, such as Dixon Center and areas around Dixon Arena, 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 Illinois 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 Dixon, Dixon 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.
