Yesterday, the Port Authority officially announced that it would give the public updates of World Trade Center construction progress through YouTube and Flickr accounts. The Port Authority's press release explains, "While subscribers to the Port Authority's World Trade Center web site already have access to up-to-the-minute updates, milestone reports, picture slideshows and videos, the new social networking hubs will allow even more picture and video content to be disseminated to a much broader audience. The new online initiatives support the Port Authority's mission to provide transparent, timely information about construction at the World Trade Center, and will make images and videos more accessible to constituents throughout the region and the world."

Above are some recent photographs plus ones of the transit hub designed by Santiago Calatrava. And below is a video taken a few days ago from the fifth floor of the future One World Trade Center (aka Freedom Tower).
