Interstate 240

Interstate 240 (I-240) is a key auxiliary route in the Interstate Highway System, serving as a bypass or beltway around major urban centers. There are two main highways designated as I-240 in the United States—one in Oklahoma City, Oklahoma, and another in Memphis, Tennessee. Both serve as crucial connectors that help divert traffic around city centers, reduce congestion, and facilitate access to intersecting routes.

In Oklahoma City, I-240 forms a partial beltway around the southern and eastern portions of the city. The highway begins at Interstate 44 (I-44) in southwest Oklahoma City and runs eastward, intersecting major routes such as I-35 and US-77, before curving north and merging with I-40 near Del City. It plays a vital role in connecting residential, commercial, and industrial areas and serves as a major truck route.
