… is Central Expressway in the Bay Area. My favorite is the Edens Expressway in Chicago. No relation that I know of.
Central sneaks inbetween 101 and 280 and if you need to avoid either, say during rush hour, then it is dang near perfect. There ARE some stoplights at cross streets which can slow your average speed but they’re certainly nicer to deal with than stop-n-go traffic.
If I were a skunk though, I’d be avoiding it like the plague. I saw two plastered on the road within a coupla miles of each other.
