The agency began wrapping the fence that surrounds the 16-acre site with vinyl mesh Sunday.

The fence wrapping will have renderings of some of the buildings being constructed at the site, like the Freedom Tower and the World Trade Center Transit Hub and it will provide information about construction progress.

The eight-foot high wrap will also have directions to help walkers navigate their way around the surrounding 12 blocks.

"A lot of tourists come down here, they don't understand what will happen here," said Community Board 1 member Catherine McVay Hughes. "They know there have been a lot of controversies, a lot of stories, but they want to see what is actually happening. And those photographs will let people know what is happening at the site."

Passersby agreed that they want to know more about progress at the site.

"You want to know when it's going to be finished and what it's going to look like so," said a New Yorker. "The fact that you're getting info could give you a better idea of what it's like and when it's going to finish."

Crews are also repainting the cement barriers and installing soundproofing material and netting on the fence to prevent construction dust and debris from blowing into surrounding neighborhoods.

"It's a lot of work, it's a lot of communication. It's very important, obviously," said Carl Passeri of Port Authority. "A lot of involvement with different groups, make you feel like they're part of the process like they need to be - it's a continuous effort."

The Port Authority expects fencing around the entire site to be covered with the new signage by Thanksgiving. The agency says it will periodically update the signs as the project progresses.
