Carmaggedon leads to significantly better air quality

As Los Angeles-area residents were preparing for “Carmageddon II” – the second scheduled closing in two years of 10 miles of Interstate 405, the busiest highway in the country, to complete bridge work – research findings were released showing almost instantaneous improvements in air quality during the original Camageddon in July 15-17, 2011. Unfortunately, the effect was reversed soon after the freeway re-opened.
