There is a bus stop on top of a building in Center City.

Specifically, there is a bus stop for SEPTA Routes 2, 9, 12, 21, and 42 on top of 1529 Walnut Street.

In terms of odd things stacked on each other, this ranks pretty high. Maybe not goat on a cow high, but still: high. Literally six stories high.

The building’s owner, Pearl Properties, is currently redeveloping it and the neighboring property. As part of the construction, Pearl is doubling the building’s height. When Inga Saffron praised the project’s design in February, the Pulitzer Prize-winning architectural critic did not mention any plans for mid-level terraced transit or a Claes Oldenburg-esque sculpture, leading PlanPhilly to believe that this was a temporary detour for the bus shelter.
