Interstate 238

Template:Routeboxca2 Interstate 238 is a short (2.23 mi/3.59 km) Interstate Highway in the San Francisco Bay Area, California. Its western terminus is at I-880 in San Lorenzo and its east end is at I-580 in Castro Valley, California, with CA 238 continuing south. I-238 is the only three-digit Interstate that does not have a two-digit "parent"; there is no Interstate 38 (and even if there was, it would go well south of the Bay Area). The number was chosen by Caltrans, who wanted an Interstate for part of CA 238, but at the time there was no available number for a "child" of I-80 (280 to 980 were in use, and there is a CA 180). I-480 is now free thanks to the demolition of the Embarcadero Freeway.
