Los Angeles-San Bernardino Inter-County Transit and Rail Study

Inter-County Transit and Rail Banner

The Southern California Association of Governments (SCAG), in cooperation with the San Bernardino Associated Governments (SANBAG) and the Los Angeles County Metropolitan Transportation Authority (Metro), is beginning a transit and rail planning study for the corridor connecting the eastern San Gabriel Valley in Los Angeles County with the western San Bernardino Valley in San Bernardino County.

A number of significant transportation improvements have been or are currently being planned in this corridor, including Metro Gold Line light rail transit, Metrolink San Bernardino Line commuter rail, bus rapid transit and Interstate 10 carpool and ExpressLanes. SCAG is seeking to develop a coordinated transit and rail strategy that best serves the transportation needs of the residents, workers, and businesses that rely on this corridor.

The study’s objectives are to:

  • Understand the market for transit and rail travel in the corridor, including travel to and from Ontario International Airport (ONT),
  • Estimate the potential benefits and costs associated with different transit and rail improvement options for the corridor, and
  • Recommend a path forward for cost-effective transit and rail improvements, with a focus on coordinating plans for the Metro Gold Line, Metrolink, and access to ONT.

Inter-County Study Process

The Inter-County Study will evaluate the current and future travel needs in the corridor and will make recommendations concerning the optimum mix of different services, including commuter rail, light rail transit, bus rapid transit, and express bus service on the Interstate 10 carpool and ExpressLanes facilities. Potential direct transit and rail connections to ONT will also be identified and evaluated. The study conclusions will be presented to the SCAG Regional Council for approval and the approved recommendations will then be forwarded to Metro and SANBAG. As the implementing agencies in their respective counties, Metro and SANBAG have the discretion to advance any recommended strategies into project development, engineering, and environmental phases consistent with federal and state requirements.

Public Involvement

There will be ongoing opportunities including an on-line survey for public involvement in the study. Two rounds of community meetings will be scheduled at key stages in the study to share information and solicit input and feedback from residents, businesses, and other stakeholders along the corridor.
