The U.S. Supreme Court has declined to hear a case regarding the Indiana Toll Road.

Truck drivers filed a lawsuit, claiming a 2018 increase in tolls on the Indiana Toll Road was unconstitutional. The increase was 35 percent on “heavy trucks,” which are those with three or more axles.

Earlier this year, the U.S. Court of Appeals ruled that it was constitutional, adding “truckers who want to avoid the tolls can use the many free roads in Indiana.”

They also said “citizens of Indiana who use the Toll Road to haul freight from Elkhart to Gary pay the same rate per mile, per axle, as do citizens of Wisconsin who haul freight from Ohio through Indiana to Illinois and beyond.”
