What role do major streets play within the Major Street Hundred Blocks system?

• A. They serve as the primary routing lines for describing locations and measuring position along the grid
• B. They are decorative
• C. They are irrelevant to location descriptions
• D. They define only street names

Answer: (A)

The main idea is that major streets form the spine of the Major Street Hundred Blocks grid, acting as the primary routing lines for describing where a location is and for measuring position along the grid. They anchor distances and directions, so you describe a spot by how far along a major street you are and by its relationship to cross streets between those anchors. This makes locating any point consistent and scalable across the city, since every block count or address is tied to those reference lines. The grid isn’t decorative or irrelevant, and it isn’t only about street names—the major streets provide the framework for precise location descriptions and navigation.
