Spring Lake, Michigan regulations require all heavy haul operations to comply with the Michigan Department of Transportation (MIDOT) guidelines as well as local ordinances administered by the Spring Lake Department of Transportation (SPRDOT).

Heavy haul permits are required for any load exceeding 12 feet in width, 16 feet 0 inches in height, or 159,913 lbs in gross vehicle weight. These dimensions are strictly enforced throughout Spring Lake, particularly in high-traffic areas.

Special consideration must be given to route planning to avoid Spring Lake Commercial Zone and the vicinity of Spring Lake Basin, which have infrastructure limitations or heavy pedestrian traffic that may impede oversized loads.

Escort vehicles are required for oversize loads exceeding 14 feet in width or 13 feet 6 inches in height on highways and certain city streets. The Michigan State Police often require escorts for loads that are particularly large or heavy.

For movements within Spring Lake, the Spring Lake Department of Transportation may mandate police escorts for oversize loads, especially during peak traffic hours. Scheduling these escorts requires advance notice, typically at least 30 hours prior to the move.

Permit applications in Spring Lake 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 Spring Lake, a traffic management plan may also be required as part of the application process.

Spring Lake has strict time-of-day restrictions for oversize loads, generally prohibiting movements during peak hours (7-9 am and 3-5 pm, Monday-Friday).

Seasonal restrictions apply during major events like the the Spring Lake Annual Celebration and the the Spring Lake Spring Parade, which may impact routing and scheduling.

Certain neighborhoods, such as Downtown Spring Lake and areas around Spring Lake Shopping 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 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 Spring Lake, Spring Lake 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.
