The committee planning the Sept. 11th Memorial Walkway of Southern Illinois unveiled the design.The centerpiece will be a 32-foot-long, 7,100-pound piece of steel recovered from the World Trade Center. It was delivered to Belleville by the Port Authority of New York and New Jersey after the organizers applied to receive the artifact.The group aims to complete the memorial by September. The memorial will be placed on the grounds of the Belleville Fire Department's administrative offices and engine house at the intersection of Illinois 15 and Illinois 159.The memorial will consist of four main parts: an entrance plaza with benches and restrooms; a memorial walkway that will serve as a timeline of the Sept. 11 events at the World Trade Center, the Pentagon, and Flight 93; a concrete memorial to Flight 93; and what the committee is calling "Ground Zero Artifact Plaza," which is where the steel column from the fallen World Trade Center will be on display.The group has not said how much money they need to raise to make the memorial a reality, but members are optimistic. The project will not require city dollars.For more information or to donate, visit www.wtcmemorial.us or send donations to: Sept. 11 Memorial Walkway of Southern Illinois, P.O.
