Absolutely! It was dumber than dirt to build the Beltway with so few non-intersecting crossovers - if you work ANYWHERE inside the Beltway, you're stuck on the same few roads that lead to interchanges whether you actually need to be ON the B'way or not. I believe there are only two crossovers in Virginia that don't have interchanges - Idlewood over in Falls Church and one in Springfield whose name escapes me.
BTW, those other overpasses, et al, weren't built because there was nothing out here. Then, one day, Maryland changed all it's property tax laws and linked them into the income tax system and Northern Virginia became a very popular place to live and have businesses.
Maryland hasn't had much economic growth since then, plus they only elect corrupt politicians to office over there.
BTW, Springfield also has the COMMERCE STREET bridge over I-95, and the Spfld.Bps (Springfield Bypass) bridge.
