Transportation

Roads

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), and has two exits less than a half mile awa. 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.
