I-10 between Santa Fe Avenue and Crenshaw Blvd. (Los Angeles, Calif.)

Of the three worst, most dog-legged corridors in Los Angeles, I-10 sits unprettily in the middle. This 6.9-mile stretch of the interstate causes 6.9 million lost hours annually due to delay—that’s right, 1 million dead hours per mile—to the tune of more than 2 million wasted gallons of gas and $187 million in time-dollars siphoned out of California’s fledgling economy.
