Question: What was the name of the massacre that took place on Florida State Road 24 in 1923?
Sentence (from "Florida State Road 9"): While SR 9 is mainly used as a hidden state designation for Interstate 95 from the Golden Glades Interchange in Miami Gardens to the Georgia border (near Yulee, Florida), a signed SR 9, which is locally known in the Miami area as West 27th Avenue, Unity Boulevard, and historically Grapeland Boulevard, extends 13 mi from the Coconut Grove section of Miami to the Golden Glades Interchange (where the unsigned portion continues northward along I-95).
Relevant evidence: No
