In 2016, this Project 911up sculpture was placed on the original experience of the impactful Stephen Siller Tunnel to Towers traveling exhibit vehicle.In 2025, that original vehicle was retired.  A new exhibit vehicle was then built and returned to the road.  This is one of the most impactful of all of our memorials.  To be able to reach so many people who could not otherwise travel to New York, Pennsylvania or the Pentagon, we are honored to have the opportunity to reach so many.
