Which road is located at 21000 E?

• A. Harrah Rd
• B. Pottawatomie Rd
• C. Luther Rd
• D. Triple X Rd

Answer: (A)

In the Major Street Hundred Blocks system, each major road sits at a specific block coordinate with an E or W indicating the direction from the central baseline. The number shows how far from that baseline the road is, in thousands of blocks. So 21000 E points to the road that sits on the 21000 block east of the baseline. Harrah Rd is the corridor that lines up with that exact coordinate in this grid, which is why it’s the correct match. The other road names correspond to different block numbers, so they don’t sit at 21000 E.
