Residents can share their opinions next month on a proposed 4.2-mile underground shuttle system that would carry passengers between a Rancho Cucamonga train station and the Ontario airport. The $538.5 million project would create a tunnel between Rancho Cucamonga’s Metrolink Station — a planned station for a high-speed train to Las Vegas — and Ontario International Airport. The fuel-free shuttles would run below Milliken Avenue and East Airport Drive, aiming to reduce traffic congestion and improve accessibility to the airport. Omnitrans, the San Bernardino Valley’s public transportation agency, would operate the system, which would put riders on shuttles through a tunnel that’s 70 feet below the surface.

Negotiations with San Bernardino County Transportation Authority officials began in February 2021. However, after the Boring Co. made a business decision not to continue down that path, the deal was called off. The authority is working to choose a contractor to build the project, spokesperson Tim Watkins said. The project includes the construction of three shuttle stations, two of which would be at the airport, located across from Terminals 2 and 4. The third would be at the Rancho Cucamonga Metrolink Station. This Metrolink station will be the depot for Brightline West, a high-speed rail line set to begin service in 2028 and run from Rancho Cucamonga to Las Vegas, with stops in Hesperia and Apple Valley. The proposed ONT Connector project would offer an alternative for airport employees and travelers seeking a different option to driving to the airport, the release states. The shuttles would be automatically controlled with no staff on board and would have self-service kiosks for check in. After departing a station, shuttles would travel down a ramp to enter the tunnel and then travel up another ramp at the end of each ride to reach its destination. Between trips, the electric shuttles would return to their starting point to recharge.

The public can review environmental documents until Monday, Dec. 2.  Feedback must be received by Dec. 2 for consideration during the environmental phase, according to the authority.
