T7R2 Challenge (Encyclopedia): VOLUME A: ARCHITECTURE
I’m making another pair of these and these. I’m not over pretzels yet.
These socks will be yellow in honor of the Three Sisters bridges of Pittsburgh which answers the Architecture challenge in Nerd Wars.
The first photo is a picture I took of my brother taking a picture of the Roberto Clemente bridge. The second photo is the picture my brother is taking in the first picture.
Many of the bridges in the Downtown area are yellow, either constructed as such or painted afterward, to match the city’s official colors of black and yellow.
The Three Sisters are three very similar self-anchored suspension bridges spanning the Allegheny River in downtown Pittsburgh, Pennsylvania at 6th, 7th, and 9th streets, generally running north/south. The bridges have been given formal names to honor important Pittsburgh residents:
- Roberto Clemente (6th Street Bridge)
- Andy Warhol (7th Street Bridge)
- Rachel Carson (9th Street Bridge)
The Three Sisters are historically significant because they are the only trio of nearly identical bridges, as well as the first self-anchored suspension spans, built in the United States. They are among the only surviving examples of large eyebar chain suspension bridges in America, and furthermore, unusual for having been erected using cantilever methods. The bridges’ design was viewed as a creative response to the political, commercial, and aesthetic concerns of Pittsburgh in the 1920s.
