State Route 259 (SR 259) is an approximately 1.48-mile (2.38 km)state highway in the U.S. state of California, serving as a freeway connector between I-215 and SR 210 in San Bernardino. It has one complete interchange (Highland Avenue) and one partial interchange (E Street, northbound only).
Route description
SR 259 splits off from I-215 as a full freeway and continues north, interchanging with Highland Avenue. SR 259 then turns east and has a partial interchange with E Street before merging with SR 210. SR 259 thus provides a route for traffic to move between I-215 northbound and SR 210 eastbound as well as from SR 210 westbound to I-215 southbound; the interchange between SR 210 and I-215 does not provide these movements.[2]
Almost all signage along the route either mention "To I-215 south" or "To SR 210 east" instead of SR 259, including the exits from SR 210[3] and I-215,[4] respectively, the freeway entrances from Highland Avenue,[5][6] and an overhead guide sign along northbound SR 259.[7] Since 2022, Caltrans had erected SR 259 reassurance markers just beyond the start of the entrance ramps from SR 210[8] and I-215.[9]
SR 259 is part of the California Freeway and Expressway System,[10] and is a freeway for its entire length,[2] and is part of the National Highway System,[11] a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration.[12]
History
The portion of SR 30 between I-215 and SR 259 did not exist in the 1960s-1970s, and traffic used SR 259, which was then designated as SR 30. Prior to its role as a state highway, the route followed by SR 259 formed a portion of the Santa Fe "Kite-Shaped Track" which looped throughout Southern California, including through communities of the eastern San Bernardino Valley.[13]
Exit list
The entire route is in San Bernardino, San Bernardino County.
