All oversize loads entering Griffith, Indiana must conform to the requirements set by the Indiana Department of Transportation (INDOT) and the Griffith Department of Transportation (GRIDOT).

In general, any vehicle over 11 feet in width, 15 feet 6 inches in height, and within the super heavy weight class (over 221,192 lbs) should obtain an oversize load permit from the INDOT and potentially additional permits from GRIDOT.

To navigate the complexities of Griffith's infrastructure, it's crucial to plan routes that avoid sensitive areas like the Griffith Marketplace and major construction zones along the Griffith Tech Hub area.

In Griffith, Indiana, loads wider than 16 feet or taller than 15 feet 6 inches must be accompanied by certified escort vehicles. Additional escorts may be required based on the specific route and time of travel through urban centers.

Griffith regulations state that police escorts must be arranged at least 30 hours before transport for loads that will impact major thoroughfares or require temporary traffic control measures.

The Indiana Department of Transportation manages the primary application process for oversize permits, with supplementary permits required from Griffith Department of Transportation for transit through Griffith limits.

Required documentation for Griffith 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.

Griffith has strict time-of-day restrictions for oversize loads, generally prohibiting movements during peak hours (6-8 am and 3-5 pm, Monday-Friday).

Seasonal restrictions apply during major events like the the Griffith International Show and the the Griffith Winter Show, which may impact routing and scheduling.

Certain neighborhoods, such as Griffith Center and areas around Griffith International Airport, 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 Indiana 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 Griffith, Griffith 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.
