The cost of driving on the Indiana Toll Road is going up an average of 2.67 percent on July 1 for drivers without E-ZPass transponders.
The cost of driving a car the full length of the toll road will be $10 — up from the current $9.70.
The toll for a typical five-axle semitrailer going the 157-mile length of the highway will be $39.70 — up from its current $38.70.
Rates for drivers with transponders will remain unchanged through 2016.
The yearly increases are stipulated in ITR Concession Co.’s 2006 lease agreement for the toll road when its parent companies paid the state of Indiana $3.8 billion for the right to operate the road and collect tolls for 75 years.
ITR can raise tolls each July 1 by either 2 percent or more if the increase in the consumer price index or the increase in U.S. gross domestic product is higher. This year’s increase is based on the increase in the GDP.
ITR spokeswoman Amber Kettring says the agreement protects users by limiting the increases.
“There’s no surprises; users know it’s going to be this way each year,” she said.
Toll revenues are used for the operation and maintenance of the Indiana Toll Road, Kettring said. ITR has several major construction projects under way, including the complete reconstruction of two Lake Station ramps between the toll road and the Borman Expressway.
Tolls hadn’t been raised on the Indiana Toll Road for more than 20 years when the state boosted the tolls in early 2006, just before the lease with ITR went into effect.
