Measure I
State Route 210 - Foothill Freeway
Elected representatives, transportation industry officials and family and friends of the late Congressman George E. Brown
snip the ribbon to commemorate the upcoming opening of State Route 210 through Rialto and San Bernardino.
This section of freeway was named in honor of the congressman.
The Foothill Freeway, also known as State Route 210, is now open to motorists and serves as a new east-west connection between San Bernardino and Los Angeles counties. The entire Route 210 extension stretches 28.2 miles through the cities of La Verne, Claremont, Upland, Rancho Cucamonga, Fontana, Rialto and San Bernardino.
With eight lanes – three lanes plus a carpool lane in both directions – the freeway was designed to provide a new route for east-west travel and help relieve congestion on Interstate 10 and on surface streets, including Baseline, Foothill Boulevard, Highland Avenue, Mountain Avenue, Haven Avenue, Sierra Avenue and others.
Air quality improvements also are a goal. The freeway is helping — and likely will continue to help — eliminate much of the start-and-stop travel on existing city streets, thereby reducing pollutants. With fewer cars sitting idle at traffic lights, this region may see cleaner air in the future. The new freeway includes carpool lanes, which are designed to move more people in fewer vehicles. Carpool lanes help reduce traffic congestion and air pollution, two benefits for the area.
As project partners, SANBAG and Caltrans shared in the design, funding and construction of State Route 210. The freeway is expected to hold an average of 163,000 vehicles per day, now that the final eight miles are complete. The final eight miles of the freeway through Rialto and San Bernardino cost approximately $233 million. This cost includes environmental work, design, right-of-way acquisition, utilities and construction costs. See a project cost summary. Funding for the freeway was provided in part by Measure I, the half-cent sales tax for transportation improvements in San Bernardino County. State and federal funds also were used to build Route 210.
Project History
Planning for the freeway began in 1948, when community leaders identified the need for a new east-west corridor through the region. Then known as State Route 30, the project endured years of delay due to funding problems. The passage in 1989 of Measure I, San Bernardino County’s half-cent transportation sales tax, helped provide the local funds needed and allowed work on the Foothill Freeway to begin in earnest.
Construction on the first 20 miles of the freeway — from La Verne to Fontana — started in 1998. On August 20, 2001, six miles of the new freeway opened between Rancho Cucamonga and Fontana. Another 14 miles opened between La Verne and Rancho Cucamonga on November 24, 2002. The last eight miles of the freeway — through Rialto and San Bernardino — opened on July 24, 2007.
