The final of the Three Sisters is the 7th Street Bridge.  This one is named after Andy Warhol, which makes since as the Andy Warhol Museum is located about two blocks from the northern end of the bridge.  Another attraction on the northern end is the “new” Alcoa building.  Alcoa, an aluminum company, moved from their skyscraper downtown to this blue glass, wavy building in 1998 (the building on the right in the picture above).  The former Alcoa Building downtown (which people still call the Alcoa Building) is unusual with its aluminum walls and pod-like windows.  It was turned over to a consortium of non-profit groups, but has lately been plagued with high vacancy rates.  A recent newspaper article announced a plan to convert the upper portion to apartments and retain the lower portion for the existing tenants.  I haven’t been inside the old building, but the new one is quite swanky.  It reminds me a bit of a building used in the first Jason Bourne film for the headquarters of a firm that sells giant yachts to billionaires.

The 7th Street Bridge was the first of the Three Sisters to be built in 1926.  The 6th Street Bridge, aka Roberto Clemente Bridge, was built downriver (see June 14th post) and the 9th Street  Bridge, aka Rachel Carson Bridge, was built upriver (see June 21st post) a few years later.  Its location in-between the other two bridges means that the views from it are not much different.  The view upstream is almost identical to that from the 9th Street Bridge, except that the 9th Street Bridge is added to the mass of bridges, making the view more cluttered.  Downstream, there is still a nice view of Mt. Washington and a good view of Kayak Pittsburgh under the 6th Street Bridge.
