Special consideration must be given to route planning to avoid Port Arthur Arena and the vicinity of the Port Arthur Financial Center, which have infrastructure limitations or heavy pedestrian traffic that may impede oversized loads.

Escort vehicles are required for oversize loads exceeding 16 feet in width or 13 feet 0 inches in height on highways and certain city streets. The Texas State Police often require escorts for loads that are particularly large or heavy.

Seasonal restrictions apply during major events like the the Port Arthur Annual Tournament and the the Port Arthur Cultural Games, which may impact routing and scheduling.
