West Florissant Avenue south of O’Fallon Park goes down to two lanes, much as most major streets in St. Louis once were. For whatever reason, the major boulevard plan did not extend up to this stretch, instead turning off onto Natural Bridge (via Palm, technically).
Update: The buildings above were demolished for a plaza by the fall of 2019.
It’s a sad stretch, featuring both active funeral homes and row after row of abandoned buildings, many showing signs of life just in the last couple decades, if the fonts on their faded signs are any indication. I wish College Hill was doing better.
