Immense, overwhelming elevated structures should ideally be avoided at all costs, but the all costs part usually takes priority to the detriment of long-term sustainability.

The tracks are no problem and no impediment for the future urbanization of Tysons. There is plenty of room to build in Tysons and the viaduct is not going to stop that. Bridges will be fine.
Tysons will never be some kind of urban utopia like a real downtown of a city ever, cause it's bisected by very wide busy roads that are anti-urban. The rail-line being tunnel or viaduct is not the main determinant. The street pattern is. It's a suburban hell hole.
