It's about time! After a prolonged (and unnecessary) moratorium on construction of the subgrade 9/11 museum at the World Trade Center site, which will delay the opening by at last one year, the 9/11 memorial foundation and the Port Authority of New York & New Jersey have come to terms about costs and responsibilities.

More than nine months of a construction moratorium! It's an embarrassment. Observers were wondering if the Mayor Bloomberg, who chairs the foundation, and New York State Gov. Cuomo—the two main hagglers— had forgotten who the enemy actually is!

Stay tuned for an ENR news story on the progress at Ground Zero. Meanwhile, here's the mayor's statement. Also, the memo of understanding is available on the N.Y.C. website.

"I'm very gratified that on the eve of this important anniversary we are able to announce an agreement that will ensure the completion of the 9/11 Museum. As Chairman of the 9/11 Memorial and Museum board, which is made up of supporters and family members who so successfully opened the completed Memorial last year, my goal during this period has been to get construction on the museum restarted. This agreement ensures that it will be restarted very soon and will not stop until the museum is completed. The museum is important to the families of those who died on 9/11 - they've contributed photos and memories of their lost loved ones, who deserve a thoughtful tribute. The museum is important to the historical record and will preserve materials and artifacts of great significance that tell the story of what happened on that terrible day. The museum is important to the country and the world because it helps us remember that freedom is precious. This agreement represents a meaningful victory for the families, and I thank Governor Cuomo, Governor Christie and the Port Authority for their cooperation."
