#2, Hawthorne Bridge, focus on the circle between the east-bound ramp and the west-bound ramp

Here's the same circle from yesterday's photo--no snow because I took the photo on September 14, 2011,standing on SE MLK which is the street where the UPS truck was located in yesterday's photo. I couldn't imagine the purpose of digging up everything. The west-bound approach ramp for the Hawthorne Bridge is just beyond the tree beside the CAT. You can see a bit of the structure between the two green trees on the left of the photo. And those narrow horizontal rectangles to the right of the CAT are guard rails on the ramp. Notice that all of the shrubs from yesterday's photo have been removed.
