Construction continues at a rapid pace and the Alley building is one of several active sites. When this photo was taken we counted ten construction cranes.
The taller building to the left is the Duke Energy Center. The building, in the reflection, is the Bank of America Tower.
Following is a link to the Alley Charlotte Center website. The construction site is at the intersection of Tryon and Stonewall.
