Springfield became a major retail destination with the opening of the Springfield Mall (now Springfield Town Center) in 1973–75 (the second regional shopping center in Northern Virginia after Tysons Corner), as well as the Springfield and Brookfield shopping centers. The 1980s and 1990s saw the expansion of retail and high-density housing in the area, at least until the opening of the Franconia-Springfield Parkway in 1996, and the Franconia-Springfield Metro and Virginia Rail Express Station in 1997. The mall was renovated and re-opened in 2014.
