A Santiago Calatrava-designed commuter concourse underneath the World Trade Center site that has been closed since the September 11 attacks reopened to commuters today. The opening of the passageway marks a major milestone in the area’s redevelopment and it offers convenience for commuters. The underground passageway connects the PATH station entrance on West Broadway and Vesey Street with Brookfield Place, which will eventually include retail and dining. The 8,000 square foot facility is complete with two lattice supports beams on either side and six escalators, giving the public access to the tunnel. The approximately 600-foot-long underground concourse, which features 40,000 square feet of Italian marble, will house stores and restaurants on two levels, by 2015.
