These lanes are part of the larger Southern California carpool lane network, which accounts for more than 654 lane miles in the metropolitan area. Most of the county's carpool lanes have been designed and constructed with funding from San Bernardino County's half-cent sales tax, Measure I, as well as other federal and state funding sources.

  • A 9.9-mile segment of Interstate 10 in Ontario and Montclair that opened in January 2000.

  • 8.5-miles State Route 71, the Chino Valley Freeway that opened in 1997.

  • A 10-mile segment of State Route 60 in Chino, Ontario, and the unincorporated area of San Bernardino County that opened in 1997.

  • A 23-mile section of State Route 210 from Upland to San Bernardino that opened in various segments between 2001 and 2007.
