The tree's official name is "El Palo Alto".
Hey, it's the Palo Alto redwood. One of the most iconic trees in that part of the state; lovely photos of the bridge here as well.
Thank you for noting the correct city. Also, this bridge crosses the creek bordering both counties, thus the listing in two counties.
Well, the creek is called San Francisquito, and the bridge is in Palo Alto, not East Palo Alto, which is a different city, in a different county!
