State Route 644 is a secondary state highway in southern Fairfax County, Virginia. It is the closest main east-west road that is south of the Beltway. It is known primarily as Franconia Road east of I-95, and Old Keene Mill Rd west of I-95. Its intersection with I-95, which is right near the Springfield Mall, was part of the major eight-year Springfield Interchange rebuilding project that was completed in July 2007.
