Over 16′ wide, over 15′ high, or over 200,000 pounds are usually allowed to move 8:30 a.m. – 3:30 p.m. Monday through Friday, but other provisions may apply. Overweight only loads can travel 24/7.

TOLL ROAD: Maximum dimensions without a state permit are 12′ wide, 14’6 height, 53′ trailer and load, 90,000 pounds gross weight. This is for routes/loads using only the toll road. Loads over 10′ wide are restricted to daylight hours only. 12′ wide loads are allowed to run weekends except certain holidays. Toll charge is by number of axles and miles. Escort requirements are the same as for other Indiana divided highways.
