September 12, 2013 Redding CA.

Today we drove out to Shasta Dam  and Power Plant which is now 75 years old.
Built during a seven year period between 1938 and 1945, the damn is a 602 foot 
high concrete gravity damn, providing flood control, power, and water supply 
benefits

We went 43 floors down into the damn into a gallery, what they call the hallways that 
allows inspections to take place inside the entire damn structure.

Power generated by the hydro turbines can provide enough power for the 
city of San Francisco and is used to meet demands to prevent brown outs.

We then proceeded to pick up a couple geocaches before making our way 
over to Sundial Bridge.

The Sundial Bridge at Turtle Bay crosses the Sacramento River in the heart of Redding, California. Opened July 4, 2004, the bridge links the North and South campuses of Turtle Bay Exploration Park and serves as a new downtown entrance for Redding’s extensive Sacramento River Trail system.

The bridge celebrates human creativity and ingenuity, important themes of the 300 acre Turtle Bay Exploration Park. The steel, glass, and granite span evokes a sense of weightlessness and the translucent, non-skid decking provides for spectacular viewing at night. The bridge is also environmentally sensitive to its river setting. The tall pylon and cable stays allow the bridge to avoid the nearby salmon-spawning habitat there are no supports in the water while encouraging public appreciation for the river. Plazas are situated at both ends of the bridge for public use; the north-side plaza stretches to the water allowing patrons to sit at the river’s edge.

In addition to being a functional work of art, the Sundial Bridge is a technical marvel as well. The cable-stayed structure has an inclined, 217 foot pylon constructed of 580 tons of steel. The deck is made up of 200 tons of glass and granite and is supported by more than 4,300 feet of cable. The structure is stabilized by a steel truss, and rests on a foundation of more than 115 tons of steel and 1,900 cubic yards of concrete. The McConnell Foundation, a private, independent foundation established in Redding in 1964, funded the majority of the bridge’s $23 million cost.

World renowned Spanish architect and engineer Santiago Calatrava conceived the Sundial Bridge’s unusual design, his first free-standing bridge in the United States. Calatrava has built bridges, airports, rail terminals, stadiums, and other structures around the world. His notable designs include the new PATH transportation terminal at the World Trade Center site in New York City and several projects at the 2004 Olympic Games in Athens, Greece, including the main stadium where opening and closing ceremonies were held

We were leaving the bridge and saw a couple guys flying hang gliders propelled by a motor attached to the gliders back. We spoke to the gliders and were jokingly asked if we would like to take it for a spin. The guys land and take off from a green space and we were told there were no special licensing, it looked like lots of fun.
