Around D.C., Metro Essential for Regional Growth
"Metro has also enabled some remarkable real estate development. Top example: Arlington County, Va., a mishmash of second-rate commercial roads a generation ago. Arlington decided early to put its Metro line, with seven stations, underground. That allowed major, well-planned and planted boulevards, dramatic office concentrations, and such a strong appetite for transit that bus rapid transit and light rail for Columbia Pike, a major artery, are now in the works."
