All oversize loads entering Sedan, Minnesota must conform to the requirements set by the Minnesota Department of Transportation (MNDOT) and the Sedan Department of Transportation (SEDDOT).

In general, any vehicle over 13 feet in width, 13 feet 6 inches in height, and within the super heavy weight class (over 223,111 lbs) should obtain an oversize load permit from the MNDOT and potentially additional permits from SEDDOT.

To navigate the complexities of Sedan's infrastructure, it's crucial to plan routes that avoid sensitive areas like Sedan Research Park and major construction zones along the the Sedan Tunnel area.

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

The Sedan Department of Transportation requires a minimum of 43 hours advance notice to coordinate police escorts, which are mandatory for super-loads or when traveling through congested areas of Sedan.

Permit applications in Sedan must be submitted through the MNDOT'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 Sedan, a traffic management plan may also be required as part of the application process.

Sedan 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 Sedan Heritage Celebration and the the Sedan Heritage Show, which may impact routing and scheduling.

Certain neighborhoods, such as Downtown Sedan and areas around Sedan Lake, 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 Minnesota 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 Sedan, Sedan 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.
