That's the article I was thinking of. Thanks.
I guess at that time, elevated walkways and separating pedestrians from vehicles were really in vogue. I know it worked in Minneapolis for climate reasons but in other places it was senseless, wasteful, and destructive. My hometown of Rockville, MD tore up its walkable, human-scaled downtown to put in high-rises, a shopping mall, and mounds and mounds of concrete, all set up to separate pedestrians from roads (elevated walkways, destruction of the street grid), and it was a disaster to say the least. Now it has torn down the mall and some adjacent projects, restored the street grid and constructed lower-rise buildings, and basically replaced the structure it had originally, but with overpriced upscale chain retail and restaurants.
The Prudential building is photogenic and attractive from I-95, but really has a glaringly suburban setup. I didn't even realize there was a sign for the restaurant on the outside of the building.
