While overall congestion was better, some areas went from bad to worse. And the report also predicts congestion will resume its upward march. The number of congested miles stayed steady at 21 percent over the past two years. The report predicts that by 2030, 33 percent to 41 percent of the highway miles will be congested.
This kind of thing is the inevitable consequence of all the freeway construction they did in the 70's. I never really realized (because I don't live over there) how bad the traffic is in the Western suburbs. Highways 169 and 100 are some of the most congested parts of the freeway system.
