In general, any vehicle over 12 feet in width, 14 feet 6 inches in height, and within the super heavy weight class (over 238,355 lbs) should obtain an oversize load permit from the ILDOT and potentially additional permits from HERDOT.

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

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

Required documentation for Herrick 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.

Herrick has strict time-of-day restrictions for oversize loads, generally prohibiting movements during peak hours (7-8 am and 4-5 pm, Monday-Friday).

Seasonal restrictions apply during major events like the the Herrick Heritage Exhibition and the the Herrick Summer Exhibition, which may impact routing and scheduling.

Certain neighborhoods, such as Herrick Center and areas around Herrick Shopping District, have restricted access for oversize loads. Alternative routes should be planned in advance to avoid these areas.
