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. 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 and I-215, respectively, the freeway entrances from Highland Avenue, and an overhead guide sign along northbound SR 259.

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.
