Opponents of the Kentucky TriModal Transpark have appealed a judge's dismissal of their lawsuit.
U.S. District Judge Ricardo Urbina ruled that a federal environmental impact study isn't needed, but a group of residents thinks differently.
Attorney Hank Graddy represents Warren County Citizens for Managed Growth.
He has filed an appeal with the U.S. District Court of Appeals for the District of Columbia.
Graddy hopes to have the Judge's decision reviewed and the lawsuit reinstated.
The transpark in Bowling Green would integrate rail, air and highway transportation around a mix of commercial and industrial activities.
Supporters say it could generate up to 7,500 jobs.
