OVERVIEW
PERMITS: Indiana oversize permits are valid for fifteen days.
OPERATING TIME: Permitted vehicles up to 110′ in length, 10′ wide, and 13′-6″ high and less than 200,000 pounds are allowed continuous travel seven days a week (24/7). Over 110′ long, 10′ to 14′-4″ wide and up to 15′ in height may travel seven days a week from one-half hour before sunrise to one-half hour after sunset. Between 14′-4″ and 16′ wide, Monday through Friday from one-half hour before sunrise to one-half hour after sunset. Over 16′ wide, over 15′ high, or over 200,000 pounds are usually allowed to move 8:30 am – 3:30 pm Monday through Friday, but other provisions may apply. Overweight only loads can travel 24/7.
RESTRICTED TRAVEL: No travel allowed on major holidays and holiday weekends.
TOLL ROAD: Maximum dimensions without a state permit are 12′ wide, 14′-6″ height, length over 65′, 90,000 pounds gross weight. This is for routes/loads using only the toll road. Larger dimensions can run the toll road with the state permit and an extra $50 special permit charge. Weight charges are taken care of on state permit. 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. A legal weight load, less than 12′ wide, running the toll road from Gate 21 at Portage to the Ohio line is around $30.00. Escort requirements are the same as for other Indiana divided highways.
