In general, any vehicle over 13 feet in width, 13 feet 0 inches in height, and within the super heavy weight class (over 155,215 lbs) should obtain an oversize load permit from the ILDOT and potentially additional permits from COLDOT.

To navigate the complexities of Columbus's infrastructure, it's crucial to plan routes that avoid sensitive areas like Columbus International Airport and major construction zones along the Columbus Hills area.

In Columbus, Illinois, loads wider than 16 feet or taller than 14 feet 0 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.
