State Route 259 (SR 259) is a short unsigned state highway in the U.S. state of California that serves as a freeway connector between Interstate 215 and State Route 210 in San Bernardino. It has one complete exit (Highland Avenue) and one partial exit (E Street, northbound only). Presently the route is signed as “To SR 210 East” on the northbound portion of the freeway and is unsigned on the southbound portion.
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.
Signage along the route either mention I-215 south or SR 210 east instead of SR 259, including the exits from SR 210 and I-215, respectively, the freeway entrances from Highland Avenue, and an overhead guide sign along northbound SR 259.
SR 259 is part of the California Freeway and Expressway System, and is a freeway for its entire length, and is part of the National Highway System, a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration.
This section needs expansion. You can help by adding to it. (March 2010)
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.
