Update: I revisited Bircher Boulevard in July of 2022. See North Newstead Avenue, which intersects Bircher Boulevard nearby.
Historic aerial photography reveals that Bircher Boulevard used to be just that, a tree-lined, elegant boulevard in North St. Louis, separating the Penrose and Walnut Park neighborhoods.
But then Interstate 70 came along, and annihilated it, turning Bircher Boulevard into nothing more than a sad frontage road and an anonymous exit passed by commuters.
But there are beautiful buildings lining it, giving us an idea of what was destroyed.
