If you believe that Villaraigosa has a plan that will work to fix traffic congestion, then I want to sell you the Brooklyn Bridge.
Pictured below is the daily traffic jam at 10:00 AM on Sepulveda Blvd of people who want to get on the 405 South and/or the Sepulveda Pass. This line is typically 1/2 mile long stretching back past Burbank Blvd. It takes about 20 minutes to get from Burbank Blvd to Ventura Blvd, a distance of about 3/4 miles, at which time the commuter gets into a real jam on the freeway or the pass. The traffic jam pictured below is just one of the hundreds on many L.A. streets. I'm sure I don't have to tell you that the root cause of the problem is illegal immigration population growth. Note that there is no construction going on and the traffic signal is green.
