SbX

Initial Development

Planning for the sbX BRT system started in 2004, when Omnitrans released its 2004 System-Wide Transit Corridor Plan for the San Bernardino Valley. Among the 10 preliminary corridors identified for potential BRT service, the E Street Corridor (later known as the sbX Green Line) between California State University, San Bernardino (CSUSB) and Loma Linda VA Hospital was identified as the highest priority corridor. Further planning of this route led to a one-stop extension northwest to a park-and-ride at Kendall Drive & Palm Avenue. The OmniTrans Board approved this preferred path in 2008.

Construction

Construction for the Green Line began in February 2012. It was set to finish in late 2013, but was pushed back due to ongoing construction at San Bernardino's downtown transit center. Service began in April 2014.

Omnitrans upgraded its East Valley vehicle maintenance facility in San Bernardino, including modifications to its parking lot, service bays, bus wash, and fueling facility, to accommodate the 60-foot buses, all of which have been purchased and acquired, to run on the sbX Green Line corridor.

Network expansion

The San Bernardino County Transportation Authority (SBCTA) is currently planning to grow the system to 10 BRT lines in the San Bernardino Valley.

Omnitrans has received a grant from the Federal Transit Administration to conduct an alternatives analysis for the Holt Boulevard/4th Street Corridor and the cities of Ontario and Fontana are both conducting studies on the feasibility of bus rapid transit along the corridor in their cities. Additionally, planners in Rancho Cucamonga are exploring recommendations on how to support high-density, transit-oriented development along the Foothill Boulevard corridor (Historic Route 66).

Purple Line

The Purple Line, also known as the West Valley Connector, is an under construction sbX route connecting Pomona-Downtown station to Ontario International Airport. It is expected to open in fall 2026, with 21 stations at launch along Holt Boulevard.

The Purple Line is slated to replace Omnitrans Route 82 west of the Ontario Mills mall with 15 minute frequencies.

Mid Valley Connector

The Mid Valley Connector is a planned bus rapid transit route that will connect the Purple Line with the Green Line.

Green Line

On weekdays, buses come every 10 minutes during peak hours and every 15 minutes outside of that. Saturdays have 20-minute frequencies. No service on Sundays.
