A group of people who question the official version of the September 11 terrorist attacks has adopted a stretch of highway in Missouri.

The "St. Louis 9/11 Questions Meetup Group" has agreed keep 5,000 miles of roadway free of litter in exchange for having its name on Adopt-a-Highway signs. Organizer Donald Stahl told KSDK the group decided to participate in the state program for "free publicity."

Stahl and others in his group believe that the World Trade Center in New York City was destroyed by a controlled demolition. Many followers of the so-called 9/11 Truth Movement believe the U.S. government orchestrated the 9/11 terror attacks in a false flag operation.

The Missouri Department of Transportation, which runs the Adopt-a-Highway program, is prohibited from denying applicants based on their viewpoints. The department had previously tried to prohibit a Ku Klux Klan group from participating in the program, but was forced to allow the racist organization to take part after losing a legal battle.
