The Tunnel to Towers Foundation launched its “Steel Across America” tour Saturday to mark 25 years since 9/11.

A beam from the wreckage of Ground Zero will travel to more than 35 cities across 21 states to honor the 2,977 people who died in the terror attacks.

Foundation CEO Frank Siller’s brother, FDNY firefighter Stephen Siller, died while helping evacuate people from the South Tower.

Frank Siller spoke at Saturday’s opening ceremony just steps from Ground Zero.

“This steel beam represents the best of who we are as a country. Twenty-six feet in length, over 16,900 pounds. It will travel coast to coast, across more than 10,500 miles,” he said.
