Interstate 238 - Wikipedia, the free encyclopedia (202 words) |
 | 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). |

 | There was also the intent to continue the 238 freeway south to I-680 in Fremont, where stub ramps and about 1,000 feet of the Mission Freeway were built in 1971. |
 | The newer 238 to 880 SB ramp overcrosses the 238 entrance from 880 northbound. |
 | I-238 is more amusing than irritating to me, mainly for the reaction it provokes. |
