All oversize loads entering Saco, Montana must conform to the requirements set by the Montana Department of Transportation (MTDOT) and the Saco Department of Transportation (SACDOT).

In general, any vehicle over 12 feet in width, 16 feet 6 inches in height, and within the super heavy weight class (over 202,217 lbs) should obtain an oversize load permit from the MTDOT and potentially additional permits from SACDOT.

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

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

The Saco Department of Transportation requires a minimum of 55 hours advance notice to coordinate police escorts, which are mandatory for super-loads or when traveling through congested areas of Saco.

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

Saco has strict time-of-day restrictions for oversize loads, generally prohibiting movements during peak hours (7-8 am and 3-6 pm, Monday-Friday).

Seasonal restrictions apply during major events like the the Saco Winter Convention and the the Saco Arts Convention, which may impact routing and scheduling.

Certain neighborhoods, such as Saco Center and areas around Saco 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 Montana 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 Saco, Saco 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.
