Tysons by Rail
One more train item and then I promise to stop. The Washington Post published an article the other day about making Tysons, VA less pedestrian-hostile. This would be an important preparation for Metro Rail service, which is slated if I’m not mistaken for Spring of 2063.
The Dulles Corridor Rapid Transit Project has already gone so far as to give the future Metro stations unimaginative but uncharacteristicly concise names [dead link removed 2005-12-05].
While I am skeptical that Tysons could ever be reworked as a livable downtown, some pedestrian bridges might help. Or better yet, how about a sky gondola system?

Desperate times call for desperate measures.
