Route description

[edit]

The route begins as Foothill Boulevard at the interchange withSR 210in the city ofLa Verne.SR 66 heads southeast for a few miles before enteringPomonaand turning due east. The highway continues into the city ofClaremont,passing byClaremont Colleges,before crossing intoUpland,San Bernardino County.[2]

In Upland, SR 66 passes byCable Airportto the south, continuing due east. The highway intersectsSR 83before enteringRancho Cucamonga,where state maintenance of SR 66 currently ends. Foothill Boulevard continues east through Rancho Cucamonga through an interchange withI-15before enteringFontana,and passing well north of theCalifornia Speedway.Foothill Boulevard continues east intoRialto,where the SR 66 designation resumes. SR 66 continues east intoSan Bernardino,before curving to the north as 5th Street and terminating atI-215south of downtown.[3]

California's legislature has relinquished state control of the segment from the Pomona–Claremont line east to the Fontana–Rialto line, and turned it over to local control.[4]

SR 66 is part of theCalifornia Freeway and Expressway System,[5]although it is neither a freeway nor an expressway. SR 66 is part of theNational Highway System,[6]a network of highways that are considered essential to the country's economy, defense, and mobility by theFederal Highway Administration.[7]

History

[edit]
See also:U.S. Route 66 in California

As a state route, SR 66 was added to the state highway system in the1964 state highway renumbering,from SR 30 around San Dimas to San Bernardino.[8]By 2013, the portion from east of Pomona to the eastern boundary of Rialto had been relinquished to the various cities that the route passed through.[9]

Major intersections

[edit]

Except where prefixed with a letter,postmileswere measured on the road as it was in1964,based on the alignment that existed at the time, and do not necessarily reflect current mileage. R reflects a realignment in the route since then, M indicates a second realignment, L refers to an overlap due to a correction or change, and T indicates postmiles classified as temporary (for a full list of prefixes, seeCalifornia postmile § Official postmile definitions).[1]Segments that remain unconstructed or have been relinquished to local control may be omitted. The numbers reset at county lines; the start and end postmiles in each county are given in the county column.
