The envelope, please! Here's your list of the 10 worst commutes in the Bay Area, compiled by the Metropolitan Transit Commission.

1. I-80 W to the Bay Bridge, in the a.m.
2. E-580 from 680 to Dublin in the p.m.
3. 580 around Livermore in the a.m.
4. Marin 101 S from Napa/Sonoma to 580 in the a.m.
5. 101 into San Francisco to the Bay Bridge in the p.m.
6. 92 in Alameda from the San Mateo Bridge to 880, in the p.m.
7. Highway 4 in the p.m.
8. 101 from SF across the Bay Bridge, in the p.m. (why is this different than #5?)
9. Highway 4 in the a.m.
10. (tie) 101 N in Marin, and W 80 across the Bay Bridge into SF.

A few questions: a) Why are certain symmetrical commutes worse either in the morning or the afternoon but not both? b) Why does the evening commute out of SF across the Bay Bridge get three separate entries, when the morning commute into SF gets only one? c) Why isn't 880 on this? and d) You know it's bad when a bridge collapses and the number 1 worst commute actually gets

Your thoughts? What's your least favorite commute?
