"In their $40 million draft environmental report, Caltrans and Metro claimed that the freeway would lead to a “minimal” elevated cancer risk—hardly reassuring, given that my wife’s breast cancer is in remission. The report was so wan, the Environmental Protection Agency deemed it inadequate. The South Coast Air Quality Management District went further, concluding that the tunnel would raise the cancer risk to unacceptable levels. The rates are especially high beside the 710, a major truck corridor. Trucks use diesel, spewing tiny carcinogenic airborne particles that lodge in the lungs."
"And the plan is for more trucks. In 2007, Los Angeles County officials declared that by lengthening the 710, goods could be hauled from the docks of Long Beach and Los Angeles to an “inland port”—storage yards, essentially—in the Antelope Valley."
"Build a freeway, and more drivers want to crowd onto that freeway. (The phenomenon is called “induced demand,” for all of you commuters on the 405 who’ve seen the $1.1 billion expansion quicken your rush hour by zero seconds.)"
"And when thoughts linger on the travails of Boston’s Big Dig or the tunnel-boring leviathan that’s been stuck under Seattle for two years, I remind myself that the whole thing could be moot: The agencies behind the 710 plan have vowed to consider rail and bus alternatives, too. So when the final decision is announced in mid-2017, the extension could be laid to rest."
