9. The 5
A.K.A.: Santa Ana Freeway into the Golden State Freeway
Route: El Toro Y to East L.A. Interchange, East L.A. Interchange to Wheeler Ridge
For L.A. residents making the drive to the Bay Area, getting on the 5 Freeway marks the start of a more than five-hour trip. For those heading south, the 5 is a major chunk of a two-hour trip to San Diego. Plagued with bumps, narrow lanes, morning traffic jams and nighttime congestion during its long stretch, the 5 Freeway - for what it's worth - is a long, necessary evil.
