Tennessee, Illinois regulations require all heavy haul operations to comply with the Illinois Department of Transportation (ILDOT) guidelines as well as local ordinances administered by the Tennessee Department of Transportation (TENDOT).

Heavy haul permits are required for any load exceeding 13 feet in width, 16 feet 6 inches in height, or 171,721 lbs in gross vehicle weight. These dimensions are strictly enforced throughout Tennessee, particularly in high-traffic areas.

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

Illinois law mandates escort vehicles for any load exceeding 17 feet in width or 14 feet 6 inches in height. When traveling through Tennessee, these requirements may be more stringent depending on the specific streets and neighborhoods traversed.

The Tennessee Department of Transportation requires a minimum of 25 hours advance notice to coordinate police escorts, which are mandatory for super-loads or when traveling through congested areas of Tennessee.

To apply for an oversize load permit in Illinois, companies must submit their applications through the Illinois Department of Transportation's permit portal. Additional permits for Tennessee may require submission to Tennessee Department of Transportation.

Documentation required includes detailed route plans, load dimensions, and weight certificates. For super heavy loads, a detailed engineering analysis may be necessary to ensure that the load can be safely transported without damaging city infrastructure.

Tennessee 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 Tennessee Holiday Fair and the the Tennessee Cultural Convention, which may impact routing and scheduling.

Certain neighborhoods, such as Downtown Tennessee and areas around Tennessee Bridge, 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 Illinois 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 Tennessee, Tennessee 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.
