All oversize loads entering Chattanooga, Oklahoma must conform to the requirements set by the Oklahoma Department of Transportation (OKDOT) and the Chattanooga Department of Transportation (CHADOT).

In general, any vehicle over 13 feet in width, 16 feet 0 inches in height, and within the super heavy weight class (over 278,703 lbs) should obtain an oversize load permit from the OKDOT and potentially additional permits from CHADOT.

To navigate the complexities of Chattanooga's infrastructure, it's crucial to plan routes that avoid sensitive areas like the Chattanooga Financial Center and major construction zones along the Chattanooga Lake area.

Oklahoma law mandates escort vehicles for any load exceeding 16 feet in width or 15 feet 6 inches in height. When traveling through Chattanooga, these requirements may be more stringent depending on the specific streets and neighborhoods traversed.

The Chattanooga Department of Transportation requires a minimum of 26 hours advance notice to coordinate police escorts, which are mandatory for super-loads or when traveling through congested areas of Chattanooga.

Permit applications in Chattanooga must be submitted through the OKDOT's online permitting system. Carriers should be prepared to provide comprehensive vehicle specifications, proposed routes, and transport schedules.

Applications must include certified weight tickets, dimensional diagrams, and route surveys. For loads that may impact traffic flow in Chattanooga, a traffic management plan may also be required as part of the application process.

Chattanooga 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 Chattanooga Heritage Exposition and the the Chattanooga Holiday Exposition, which may impact routing and scheduling.

Certain neighborhoods, such as Downtown Chattanooga and areas around Downtown Chattanooga, 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 Oklahoma 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 Chattanooga, Chattanooga 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.
