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

In general, any vehicle over 13 feet in width, 14 feet 6 inches in height, and within the super heavy weight class (over 195,983 lbs) should obtain an oversize load permit from the ILDOT and potentially additional permits from NAUDOT.

To navigate the complexities of Nauvoo's infrastructure, it's crucial to plan routes that avoid sensitive areas like the Nauvoo Financial Center and major construction zones along the the Nauvoo River area.

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

Required documentation for Nauvoo 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.

Seasonal restrictions apply during major events like the the Nauvoo International Celebration and the the Nauvoo Food Fair, which may impact routing and scheduling.

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