A commuter concourse underneath the World Trade Center site that has been closed since the Sept. 11 attacks is set to reopen.

The Port Authority of New York and New Jersey has scheduled a news conference at the World Trade Center PATH rail station for Thursday morning. A spokesman says the concourse will be open to commuters beginning by the evening commute.

The underground passageway runs west from the PATH station and underneath West Street. Pedestrians had been using a bridge over West Street that is being dismantled.

The renovation of the concourse is part of a nearly $4 billion redevelopment of the World Trade Center site that includes a new transportation hub scheduled to be completed by 2015.
