Distinguished Professor Emeritus of Urban Planning Martin Wachs spoke to the Los Angeles Times about California’s beleaguered plan to build a high-speed rail line that had initially sought to link San Francisco and Los Angeles. Concerns about the time required and cost of the rail’s construction continue to be raised following Gov. Gavin Newsom’s State of the State speech. “There’s an enormous amount of uncertainty,” said Wachs, a member of the peer review committee monitoring the business plans of the high-speed rail project. “You can’t be completely sure of what it will cost,” he added. “The technology changes as it’s being built, the demand pattern changes as it’s being built.”
