All oversize loads entering Donahue, Iowa must conform to the requirements set by the Iowa Department of Transportation (IADOT) and the Donahue Department of Transportation (DONDOT).

In general, any vehicle over 11 feet in width, 14 feet 6 inches in height, and within the super heavy weight class (over 197,747 lbs) should obtain an oversize load permit from the IADOT and potentially additional permits from DONDOT.

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

Iowa law mandates escort vehicles for any load exceeding 16 feet in width or 15 feet 0 inches in height. When traveling through Donahue, these requirements may be more stringent depending on the specific streets and neighborhoods traversed.

The Donahue Department of Transportation requires a minimum of 69 hours advance notice to coordinate police escorts, which are mandatory for super-loads or when traveling through congested areas of Donahue.

Applications must include certified weight tickets, dimensional diagrams, and route surveys. For loads that may impact traffic flow in Donahue, a traffic management plan may also be required as part of the application process.

Donahue 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 Donahue International Fair and the the Donahue International Show, which may impact routing and scheduling.

Certain neighborhoods, such as Downtown Donahue and areas around Donahue Historic 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 Iowa 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.
