The Minnesota Department of Transportation will also light the I-35W Bridge in Minneapolis in honor of the attack victims. It will shine red, white and blue.
Dayton issued a statement recalling the tragic day. He had served as a U.S. senator from 2001 to 2007.
The governor says he was in Washington D.C. at the time, watching on TV as the first plane crashed into the tower.
"When another plane crashed into the second World Trade Tower, we realized with horror that they were not accidents," Dayton said in the statement.
Dayton recalled watching from a hotel rooftop, seeing "black smoke pouring from the Pentagon."
“Like so many Americans, I will never forget that terrible day 15 years ago. I pray for the victims, their families, and their colleagues. I hope they might find peace, despite their immeasurable losses," Dayton added.
According to Lt. Gov. Tina Smith, 2,996 people died in the attacks.
