Mark Hornung, Senior Vice President of Strategic Projects at ALK Technologies wrote an opinion piece for Transport Topics titled Zeroing in on Tolls:
"In general, toll costs from Chicago to destinations on the East coast will account for between 8 and 19 percent of the total cost to operate commercial vehicles on these routes. The margin gets worse if going up and down the northeast corridor. The tolls here account for as much as 23 percent of total cost."
