Despite concerns from residents living adjacent to the highway that a highway widening of Route 57 would ruin their quality of life, officials from the Orange County Transportation Authority and Caltrans will not change their plan to widen five miles of highway in Orange County. The transportation officials pushing the project argue that reducing congestion will improve air quality by reducing the amount of cars sitting in traffic.
The theory that you can build your way out of highway congestion has been debunked by advocates and DOT's throughout the country. When capacity is added to a highway, the traffic lanes actually are filled up by new traffic in a matter of years because new sprawl development will lead to more traffic which will lead to calls to widen the highway again. This is called induced demand, and is proven everyday in Southern California. How have past highway widenings helped car commutes near where you live?
