Routes marked by odd numbers typically run in which direction?

Routes marked by odd numbers typically run north to south. This is a convention established in the numbering system used for highways and interstates in many regions, particularly in the United States. The odd-numbered routes are generally designed to facilitate north-south travel, connecting cities and regions along a vertical axis. This system helps drivers easily navigate and understand the orientation of the routes on a map.

In contrast, even-numbered routes are designated for east-west travel, further establishing a consistent pattern that aids in navigation and planning for road trips. Understanding this numbering system is essential for drivers as it allows them to anticipate the direction of travel based on the highway numbers they encounter.
