The trick is that it is on E. 60th Street! The streets in Broad Ripple were renumbered around the annexation of nearby areas by the City of Indianapolis from the 1910s through the 1930s. This sidewalk marking is at 60th and Carrollton Avenue [JJ24 on map]. Most of the rest of these historic street markers have been lost due to sidewalk replacements.
