ADDITIONAL INFO:
Though there are many other locations where streams are covered over and buildings built upon them, this is one of the unusual instances where the building structure is obviously more bridge-like.

The 1916 Hopkins plat map shows the A. Straab Co. Undertakers building as a masonry structure occupying two narrow lots and crossing over Saw Mill Run. The building at present is a patchwork of brick on each side of the stream with newer concrete block in the center.

In 2001-3, an Army Corps of Engineers project included deepening, realignment and streambank stabilization of 4,700 feet of Saw Mill Run. The streambanks in this area are covered with Fabriform revetments -- double layered nylon fabric forms filled with concrete grout.
