Agreed things are a mess there traffic wise further out - but - Part of the problem with DC metro is that the suburbs where it would make sense to expand the roadways are full of multi-million dollar homes owned by rich politically connected people (not just several hundred thousand dollar homes owned by mere mortals), plus you have the 4 'local' state governments (dc,md,va,fed) plus cities (e.g. chevy chase, arlington, etc) and bazillions of agencies (e.g. park service) throwing their hat in the ring too.. E.g. hypothetically, why should the northern tip of DC (and therefore the fed) pay to improve a congested road full of traffic between rockville and chevy chase? and why is my mansion being demolished and not yours etc.
