Still years away from having a permanent memorial, the temporary site where visitors go to pay their respects to those who died aboard United Airlines Flight 93 is being moved -- across the street.

Set on privately owned land in Stonycreek Township in Somerset County, the temporary memorial, which sprang up soon after the Sept. 11, 2001 crash, will move to the other side of Skyline Road after the property owner, mining company Svonavec Inc., decided to terminate the agreement it had with the National Park Service.

No one from Svonavec could be reached for comment yesterday; however, company secretary-treasurer Mike Svonavec has previously said that the temporary memorial could remain but without a written agreement.

But Flight 93 Superintendent Joanne Hanley said that won't work.

"The National Park Service does not operate public programs on private lands -- nor does the National Park Service expend money on private lands without an agreement," she said. "We can't do business on a handshake."

Instead, the temporary memorial -- which consists of chain-link fencing, a shelter, donated benches, statues and small boulders -- will be moved across Skyline Road to land owned by the Families of Flight 93, a nonprofit working group in partnership with the park service.

"We have the same mission. We have a long-standing relationship," Ms. Hanley said. "And that's to provide the public with a dignified, solemn and respectful experience at the new temporary memorial."

All of the items that have been left at the old site have been taken down and will be moved to the new site on Monday.

Barbara Black, the memorial curator, said that more than 30,000 items, ranging from ball caps, to handwritten notes to religious pieces, have been collected from the temporary memorial over the years. They are now in storage awaiting placement at the permanent memorial, expected to be opened in 2011.

"We take this very seriously. We've been entrusted by the American people to take care of these tributes in perpetuity," Ms. Hanley said.

Much of the work at the new, temporary site has already been completed. The material for the parking lot and pad have been put down -- though the gravel still needs to be compacted; the shelter has been moved; and there is a new 40-foot section of chain-link fence where visitors can leave tributes.

Access will continue to be available to the current location until the new site opens in mid-August.
