Recently, national attention was focused on the prospect of “Carmageddon” in Los Angeles brought about by the closure of 10 miles of Interstate 405 during a weekend. But the most contentious highway project in the region, the I-710 Freeway, remains uncompleted. In May 2010, after 50 years of debate and false starts, the Los Angeles
County Metropolitan Transportation Authority funded the environmental impact report for finishing with a toll tunnel the last 4.5 miles of this section of its freeway core. Currently, northbound vehicles on I-710 exit onto Valley Boulevard, where the freeway ends, and the traffic continues on local streets in Alhambra, South Pasadena and Los Angeles. The extension would link I-710 to I-210, but the final route is not settled.
