Here we see the area east of Broadway. Note the street names: "A Street" is now Fifth Street North, "B Street" is now Third Street North, and "C Street" is now 2nd Street North. Note also that there is a "Levee Avenue" between Second and Third Avenues. This is interesting because the levee is actually several blocks further south near the NP Railroad bridge.
Shown with a "2" on NP Avenue and A Street is a "public school."
