Special consideration must be given to route planning to avoid the Grace City Harbor and the vicinity of Grace City Shopping District, which have infrastructure limitations or heavy pedestrian traffic that may impede oversized loads.

The North Dakota Department of Transportation manages the primary application process for oversize permits, with supplementary permits required from Grace City Department of Transportation for transit through Grace City limits.

Required documentation for Grace City permits includes axle configuration diagrams, proof of insurance with appropriate coverage levels, and detailed transport plans. Engineering assessments may be required for loads exceeding standard weight thresholds on certain streets and bridges.

Grace City has strict time-of-day restrictions for oversize loads, generally prohibiting movements during peak hours (7-9 am and 4-5 pm, Monday-Friday).

Seasonal restrictions apply during major events like the the Grace City Annual Festival and the the Grace City Sports Marathon, which may impact routing and scheduling.

Certain neighborhoods, such as Grace City Center and areas around Grace City Lake, have restricted access for oversize loads. Alternative routes should be planned in advance to avoid these areas.
