Andy Warhol Bridge

Lars already mentioned the many bridges in his Pittsburgh posts and showed them a few.
The most famous are three almost identical bridges known as "The Three sisters" and of these three is the "Andy Warhol Bridge" the best known.

The Andy Warhol Bridge, also known as the Seventh Street Bridge, spans the Allegheny River in Downtown Pittsburgh and is the only bridge in the United States named for a visual artist.
Lars has already shown two photos of this bridge, thats why I focus on the construction of the bridge.

The Three Sisters are so-called self-anchored suspension bridges.
This type of suspension bridge has two towers (pillars)
to which the suspension cables are attached.
The bridge deck (the load-bearing portion) hangs from vertical suspenders on the suspension cables.
The end of the suspension cables here is anchored the bridge itself and not, as often, in the ground. As a result, this bridge can be moved in its entirety if you should want to move the bridge.

Photo 1 focuses on the sign with the name of the bridge and a portrait of the artist. I return to Andy when we enter the museum in a few days.
Photo 2 shows the composite suspension cable in detail. In the background one of the two pillars.
Photo 3 shows how the vertical suspenders connect the suspension cables and the bridge.
