List of U.S. Highways in Oklahoma

United States Numbered Highways in Oklahoma are part of a nationwide network of roadways passing through the 48 contiguous states. These U.S. Highways are the second-highest category of road classifications in the Oklahoma road system, just below the Interstate Highways. U.S. Highways are marked with a number contained inside a white shield in a black box. The number is generally even if the highway runs east–west, and generally odd if it runs north–south, though there are many substantial deviations from this plan.
