Ontario International Airport (ONT) Connector Project

Ontario International Airport (ONT) Connector Project

The proposed Project would construct an underground 4.2 mile single tunnel (24-foot inner diameter bidirectional tunnel) alignment to provide a direct connection between Cucamonga Metrolink Station and Ontario International Airport (ONT). The tunnel depth has been designed to be approximately 70 feet below the ground surface. The proposed tunnel alignment begins at the Cucamonga Metrolink Station and travels south along Milliken Avenue, crossing beneath 6th Street and 4th Street. At Ontario Mills Parkway, the tunnel alignment shifts to the western side of Milliken Avenue to avoid the Interstate 10 (I-10) overcrossing. The alignment continues south under 1-10 and the Union Pacific Railroad, before traveling west beneath East Airport Drive to connect to Terminals 2 and 4 at ONT. Three stations would be constructed to serve the Cucamonga Metrolink Station, ONT Terminal 2, and ONT Terminal 4. The Maintenance and Storage Facility (MSF) would be located at the northwestern comer of the existing Cucamonga Metrolink Station parking lot to support operations and provide autonomous electric vehicle storage, maintenance, and cleaning. One vent shaft would be constructed to provide ventilation for the tunnel and as a means of emergency passenger egress and first responder access to and from the tunnel. The proposed Project would operate autonomous electric vehicles to transport passengers between the Cucamonga Metrolink Station and ONT. The autonomous electric vehicles would be grouped and queued at their origin station and depart toward the destination station once boarded with passengers. After the group of vehicles arrives at the destination station and passengers deboard, new passengers would board, and the group of vehicles would return to its origin station. If no new passengers are present, empty vehicles would be returned to the origin station to pick up new passengers. The proposed Project would provide a peak one way passenger throughput of approximately 100 per hour. Operations would be managed by Omnitrans, with on-demand service provided daily from 4:00 a.m. to 1 1:30 p.m., including weekends and holidays.
