Free passes to visit the National September 11th Memorial in Lower Manhattan on the first day it is open to the public were snapped up in one hour this morning.
All 5,000 visitor tickets for September 12 were reserved through an online system at 911memorial.org,
Up to nine passes for a specific time and day can be reserved at a time through the website.
There is so much interest in the site that it has been running at slower-than-expected speeds today, and people are urged to be patient when accessing the system.
The memorial will be dedicated by public officials and families of World Trade Center victims on September 11, the day before it opens to the public.
The memorial plaza -- featuring the names of September 11th victims and the reflecting pools in the footprints of the original Twin Towers -- can only hold about 1,500 people at a time.
Even though tickets are needed, the memorial is free and visitors can stay as long as they like.
"The reservation system is absolutely a work-around that we had to develop to reflect the fact that construction continues around us," said President Joseph Daniels of the September 11th Memorial and Museum.
Many who live and work in Downtown Manhattan told NY1 they want to be among the first to see the memorial.
"Most definitely, most definitely. I was here, I lived through it, lost some friends. Yes, that would be interesting to me," said one New Yorker.
"Oh, that would be worth it. If you could actually reserve your tickets and make sure you would avoid huge crowds, I would do that, definitely," said another.
Once the reservation is made, visitors can either print the pass at home or pick it up at the September 11th Memorial preview site on Vesey Street.
