LOS ANGELES (AP) — California’s ambitious Los-Angeles-to-San-Francisco high-speed rail project will likely miss its 2022 deadline and go over its $68 billion budget, a newspaper analysis concluded. State officials underestimated the project’s challenges — particularly punching 36 miles of tunnels through the geologically complex mountains north of Los Angeles, the Los Angeles Times said Saturday (http://lat.ms/1RuLf0X). It will be the most ambitious tunneling project in U.S. history.
