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

Missouri law mandates escort vehicles for any load exceeding 15 feet in width or 14 feet 0 inches in height. When traveling through Mercer, these requirements may be more stringent depending on the specific streets and neighborhoods traversed.

Mercer 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 Mercer Film Show and the the Mercer Annual Fair, which may impact routing and scheduling.

Certain neighborhoods, such as Downtown Mercer and areas around Mercer Municipal Complex, have restricted access for oversize loads. Alternative routes should be planned in advance to avoid these areas.
