All oversize loads entering Cadillac, Michigan must conform to the requirements set by the Michigan Department of Transportation (MIDOT) and the Cadillac Department of Transportation (CADDOT).

In general, any vehicle over 13 feet in width, 15 feet 6 inches in height, and within the super heavy weight class (over 152,234 lbs) should obtain an oversize load permit from the MIDOT and potentially additional permits from CADDOT.

To navigate the complexities of Cadillac's infrastructure, it's crucial to plan routes that avoid sensitive areas like Cadillac Tech Hub and major construction zones along the Downtown Cadillac area.

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

The Cadillac Department of Transportation requires a minimum of 60 hours advance notice to coordinate police escorts, which are mandatory for super-loads or when traveling through congested areas of Cadillac.

Permit applications in Cadillac must be submitted through the MIDOT's online permitting system. Carriers should be prepared to provide comprehensive vehicle specifications, proposed routes, and transport schedules.

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

Cadillac has strict time-of-day restrictions for oversize loads, generally prohibiting movements during peak hours (7-8 am and 4-6 pm, Monday-Friday).

Seasonal restrictions apply during major events like the the Cadillac Winter Games and the the Cadillac Holiday Marathon, which may impact routing and scheduling.

Certain neighborhoods, such as Downtown Cadillac and areas around Cadillac 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 Michigan 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 Cadillac, Cadillac 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.
