Elon Musk abandoned plans for a four-mile tunnel at Ontario airport. Locals are picking it up

Travelers at Ontario International Airport in Ontario. Elon Musk’s civil engineering firm, the Boring Co., has abandoned plans for a four-mile tunnel from the Rancho Cucamonga Metrolink station to the San Bernardino County airport. Among those plans, Musk’s civil engineering firm, the Boring Co., submitted an unsolicited proposal in 2019 to the San Bernardino County Transportation Authority for a tunnel that would whisk riders from the Rancho Cucamonga Metrolink station to Ontario International Airport in just a few minutes. In April, the San Bernardino County Transportation Authority began obtaining environmental clearance and drafting a formal document for the Ontario airport tunnel, a process that typically takes around 18 months. “On the upside for SBCTA, the Boring Co. has acted as such a disrupter in the market that other companies are stepping up with innovative ideas and reduced pricing, and they’re interested in these projects they may not have been interested in before,” San Bernardino County Supervisor Janice Rutherford said.
