Highway to Hoover (Boulder) Dam, Nevada

Looking northeast. The upper photo is from the L. F. Manis collection (#100-3348) at the University of Nevada, Las Vegas, and was taken in the early 1930s. The lower photo is by me, 13 June 2011.

The highway isn't all that different, but there are now lots of high-voltage transmission towers of various vintages. I think the steel frame tower on the left dates from the dam's construction, while the pylons on the right are considerably newer. The edge of the new Hoover Dam Bypass Bridge is visible at the extreme right in the modern photo (outlined).
