Flutterby™! : The Maze

Glad I don't commute: Tanker truck overturns and ignites on I-80 to I-880 overpass, destroying it and I-80E to I-580E connector. I believe that when they completed that interchange a few years ago it was on record as some of the most expensive road anywhere, measured in millions and inches. But it's a major connector between Pleasanton, Livermore and Oakland and Berkeley and San Francisco ('though you may be able to get on to the Bay Bridge without it...).

At any rate, I hope that BART manages to leverage this one well, they've already announced free rides today in the wake of the collapse, it'll be interesting to see how the commuting situation out there evolves.
