The red stripes are shiny tiles inlaid in the cement, which makes sense so they do not have to be painted. The design of this bridge seems to show that it is intended to regulate the amount of water downstream. The holes for the water to flow through are only about 8 feet (2.4 m) high, but the markers anticipate that water could be 14 (4.25 m) feet high. The bridge will cause water to back up and flood the McCormick Ranch Golf Course and will let only the amount of water that can fit through these tunnels to flow downstream.
It is hard to imagine that in the desert, where we get only 7 inches (17 cm.) of rain per year, we need flood control projects, but we do. Heavy thunderstorms in the summer can cause localized flash floods. This bridge looks very strong. I can remember about 30 years ago there was a flood that wiped out every bridge across the Salt River bed in Phoenix except one. The Salt River is usually dry, and until the water subsided the Valley was cut in two, with people having a very hard time to get from home to work if they worked on the other side of the river bed. The one bridge that survived was the oldest of the bridges.
This week we are showing photos of the subtle beauty of nature in Yosemite National Park on our Viva la Voyage travel photo site.
