The MTA Remembrance Walk was held Sunday to honor lives lost during the 9/11 terror attacks.

The Tunnels 2 Towers Run and Walk was supposed to be held two weeks ago to honor those lost on Sept. 11, but it had to be canceled due to the COVID-19 pandemic. Sunday's event was smaller, but was held to ensure people didn't forget those lost as a result of the attacks.

MTA officials joined with the family of Stephen Siller, the firefighter who carried his gear on foot through the tunnel on the fateful morning as he rushed toward ground zero. The remembrance walk was held through the same Hugh L. Carey Tunnel to remember him and others who died that day.

The foundation has since launched the "Never Forget Virtual Challenge," which encourages people to honor the fallen in their own way.
