October 31, 2012 - Glen Canyon Dam Bridge
From the Glen Canyon Dam Visitor Center parking lot. Page, Arizona.
I am ever amazed at the engineering and human effort required to erect bridges over such treacherous and void expanses. Photographically, the art of form and function compressed into two-dimensional space - and void of color is, well, visually stimulating. I always think of our daughter Amanda when near these structures. As a civil engineer, her concentration was bridge design before a most worthy detour to raise our grandchildren..! This image is for Amanda...
Interesting when viewed in X3..
Completed in 1959 at a cost of just over 5 million dollars, the Glen Canyon Dam bridge was, at that time, the highest arch bridge in the world and the second highest bridge of any type. Fifty years later it no longer ranks even among the top forty with a height of 700 feet and length of 1028 Feet. Crossing the Colorado River about 12 miles (20 km) east of Grand Canyon National Park, the bridge was a necessary component in the construction of the massive Glen Canyon Dam, a concrete gravity arch structure that is just as large as the much more famous Hoover Dam near Las Vegas. Behind the Glen Canyon dam is Lake Powell, one of the largest reservoirs in the United States with a 1,900 mile (3,057 km) shoreline. Construction of the dam began in 1956 and ended in 1963.
Thanks for your kind remarks about our Arches National Park contribution yesterday..
