Interstate 565 (I-565) is a 22-mile-long (35 km) Interstate spur that connects I-65 in Decatur with U.S. Route 72 (US-72) in Huntsville, in the U.S. state of Alabama.
I-565 serves the cities of Decatur, Madison, and downtown Huntsville. It also provides a route to the Huntsville International Airport. The interstate forms a part of Appalachian Development Highway System Corridor V. US-72 Alternate travels concurrent with I-565 for its entire length.
I-565's connection with the rest of the Interstate Highway System occurs at its western terminus, at an interchange with I-65. The interchange was extant prior to I-565's construction; it served Alabama State Route 20 (SR-20), which previously extended eastward into Huntsville. (The interchange was rebuilt and improved as part of the I-565 construction.) From the interchange, I-565 takes a brief northerly swing to bypass the town of Mooresville before joining and subsuming the former right of way of SR-20 through rural southeastern Limestone County. Progressing eastward, as the western edge of the city of Madison it diverges slightly to the south of the former SR-20 route, traveling parallel to it a short distance away. (This portion of the old SR-20 route is now named Madison Boulevard.)
