I decided to address each of the Three Sisters separately after all and for some reason to do it out of order (which is quite unusual for me as I am generally very methodical). The 9th Street Bridge is also called the Rachel Carson Bridge. Rachel Carson was an environmentalist who grew up near Pittsburgh and attended college at the forerunner of Chatham University (one of Pittsburgh’s many universities). The bridge was named in her honor on Earth Day in 2006. Unlike the other Three Sisters Bridges, there is no specific reason why this bridge should have been named for Rachel Carson. The 6th Street Bridge (see June 14th post) renamed for Roberto Clemente, a former Pirates player, connects to PNC Park, the current home of the Pittsburgh Pirates, while the 7th Street Bridge renamed for Andy Warhol connects to the Andy Warhol Museum (see June 22 post). As far as I am aware, there is no similar connection between the location of the 9th Street Bridge and its namesake.
As far as my observations go, this bridge is the least used of the Three Sisters. The south end of the bridge is near CAPA High School (for performing arts) and the Convention Center, but the north end does not connect to any buildings or sights that seem like they attract much traffic, while the north end of the other two connect to a museum and a ballpark. In addition to the surroundings, the condition of the bridge suggested that it is not as well cared for (perhaps because there is less traffic) than the others. There are two stone pillars at each end of each of the three bridges. One of these on the Rachel Carson Bridge was almost completely covered in vines and weeds. The side facing into the bridge holds the plaque identifying the bridge and was the only side not covered in growth. On second thought, perhaps this is not due to a lack of maintenance but rather in recognition of the fact that Rachel Carson was an environmentalist.
The views up and downriver from the Rachel Carson Bridge encompass mostly the other bridges around it. Upriver are a railroad bridge, the Veteran’s Bridge (see June 24 post), and the 16th Street Bridge (see July 13 and July 14 posts). However, rising above these bridges is the Children’s Hospital in Lawrenceville, another iconic Pittsburgh building visible from multiple points around the city and displaying a color scheme as intriguing as any of the London bridges.
