Driving in Castro Valley: What to Know
Most workers here drive alone, about 66%, and only about 6% take public transit. That means your own car carries most of your daily travel, so solid coverage matters. About 74% of households own two or more vehicles, compared with 63% statewide, so many families insure more than one car and may want to ask about multi-car pricing. I-580 and SR-238 run through or near the community, and a commute that ranks sixth longest of 20 places in the county means plenty of time in traffic. About 18% work from home, which could lower your annual mileage and may help your rate.
