Actually, the N-S "street" out by Sand Springs is 111th West AVENUE. The E-W street is West 111th Street, sometimes referred to as West 111th Street South. Under the Tulsa grid system, "streets" run E-W, "avenues" N-S. Not to be confused with Courts, Places, Boulevards, and Heavy Traffic Way.
I was simply refering to the E W designations, and their placement within the the street name itself, not refering to the designation of Street, which as you said would run E-W. To include with Ave, Roads and Boulavards run N-S, where Pl, Ct and one more that I can't recall at this moment denote subsets of a specific street in any direction (21st Pl would fall between 21st and 22nd). There is a method to the street system, it's just that most people are completly unaware of it.
