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 County Transportation Authority (SBCTA) and the Los Angeles County Metropolitan Transportation Authority (Metro), conducted 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, hybrid rail, express bus and bus rapid transit and Interstate 10 carpool and ExpressLanes. The study sought 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 were 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.
