i mean, WTF does this mean?

"'The K Street Transitway can and should be a transformational project – but it was designed for a downtown that no longer exists, and it only covers a few blocks,' CM Allen said."

'a downtown that no longer exists' - Is he saying we solved congestion? No more need for bus lanes? Or buses?

'it only covers a few blocks' - Right. but they're heavily congested ones where there's also lots of space. Do you want a tunnel under Mt Vernon Sq? That's a lot of free fares.
