There are still some buildings just south of Highway 40 that were designed when Market Street still passed by their northern facades, such as the one above. But when the highway was built after World War II, they suddenly found themselves in limbo. See this aerial shot from my look at the Council Plaza development.
The rest of the area south of Scott Street is a warren of side streets with various warehouses, some of which are occupied, from the looks of it.
See parts One and Two of my Under the Viaducts series.
