Springfield Mall is a large indoor shopping mall located at the intersections of Interstate highways I-95 and I-495 (also known as the Springfield Interchange). It contains several anchor stores (including a Macy's) and a food court. This mall's DMV office was where Hani Hanjour and Khalid al-Mihdhar, two of the hijackers in the September 11 attacks, illegally obtained state identification. The mall also experienced two gang-related stabbings in 2005, and a fatal shooting in December 2007. The mall was purchased by Vornado Realty Trust in 2005, who are planning massive renovations to revive the mall. It is expected to be renamed the "Springfield Town Center", incorporating retail, specialty restaurants, housing, and office buildings. As of May 2008, many of the stores (including most of the restaurants and the AMC Theatres) have closed or relocated in preparation for the upcoming renovations. The remodeled mall is slated to reopen in 2010.
Central Springfield is dominated by the over half-billion dollar Springfield Interchange highway project, which was completed in 2007. Due to its complexity, the interchange is popularly known as the "Mixing Bowl", a name taken from an earlier interchange near the Pentagon. It includes three Interstates (I-95, I-395, and I-495), has two exits less than a half mile away, has two unconnected roads (Commerce Street and Route 644 (Old Keene Mill Road / Franconia Road) going over or under the Interstates less than a half mile away, and is further complicated by the presence of a separate, reversible high-occupancy vehicle lane passing through the center of two of the Interstates. This project was dedicated on July 18, 2007 by Virginia Governor Timothy M. Kaine. The eight-year, $676 million Springfield Interchange Improvement Project was finished on time and on budget, according to the Virginia Department of Transportation.
