All oversize loads entering Grenada, Mississippi must conform to the requirements set by the Mississippi Department of Transportation (MSDOT) and the Grenada Department of Transportation (GREDOT).

In general, any vehicle over 12 feet in width, 15 feet 6 inches in height, and within the super heavy weight class (over 160,016 lbs) should obtain an oversize load permit from the MSDOT and potentially additional permits from GREDOT.

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

Required documentation for Grenada 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.

Grenada has strict time-of-day restrictions for oversize loads, generally prohibiting movements during peak hours (6-9 am and 3-6 pm, Monday-Friday).

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