I mean it sucks, but how do you do widespread repairs? The system in 40 years old and I imagine doing it in one fell swoop is ultimately less pain than doing it piecemeal.
Chicago shut down its Red line for 5 months
LA is shutting down it's Blue line for 8 months
NYC is closing the L Train for 18 months
true, but they're closing down a whole section by choice (remember they've 'fixed' the tracks, this is about stations). If you commute from King, your backup is probably Braddock. If you drive into Huntington, King is another 10 minutes. They've decided to work on all of them at once instead of doing king and silver spring then braddock and arlington.
