This bridge is located on the campus of Phoenix Country Day School, a college preparatory school for kindergarten through high school. It is a nonsectarian school that prepares graduates for admission to the nation’s top colleges and universities. You can read more about it here.
The campus is split by a wash that is mostly dry, but during heavy rains can fill with rushing water coming off of the mountains that cut through our city.
When I stopped to take this photo, I notice that the school was celebrating it’s 50th anniversary.
