California High-Speed Rail is a planned high-speed rail system in the state of California. The planned line would connect Los Angeles with San Francisco and allow for future extensions to San Diego and Sacramento. Initial funding for the project was approved by California voters on November 4, 2008, and authorized the issuance of US$9.95 billion in bonds for the project.
The project's cost and scope have long been a source of controversy. The California High-Speed Rail Authority has estimated the project's year-of-expenditure cost at $68.4 billion (2011 estimate). In July 2014 The World Bank reported that the per kilometer cost of California's high-speed rail system was $56 million, as compared with $17–21 million per km in China and $25–39 million per km in Europe.
