Work the 9/11 National Memorial Trail Alliance is moving forward right now.
The 9/11 National Memorial Trail is a 1,500+ mile route the Alliance is actively building out. We develop the trail the way land trusts and rail-trail coalitions do — securing the grants and permits, commissioning licensed design and engineering consultants, and putting each project out to bid so qualified contractors build it to code. Here's what we're advancing right now; we update this page monthly so partners, press, and friends of the trail can follow the progress.
