Cities in the United States adopted the grid street pattern because of influential examples of gridded cities.
Grids are great for cities that expect rapid growth, making it easy to divide and sell lots.
Grid lines from national land ordinances were used to lay out cities in the Midwest and West.
Railroad companies used grid street patterns in new cities along their routes for rapid growth and profitability.
Grids provide rectangular or square lots, making surveying, subdivision, and selling easier.
