A fun, pretty place to stop while riding Cañada road. I has water and an air pump and bathrooms. Take a photo with friends.

You're not hallucinating: This monument was deliberately built in the style of ancient Greek and Roman architecture, to commemorate the Great Depression-era Hetchy Hetchy Project that brought water down from the mountains to the Bay Area. The frieze says, “I give waters in the wilderness and rivers in the desert, to give drink to my people.”

While this is an expressway, there is good room for safe riding and most of the day it isn't too heavily trafficked which makes for a great, rolling straight run
