Several special routes of U.S. Route 20 (US 20) exist. In order from west to east, they are as follows.
U.S. Highway 77 (US 77) is the shortest U.S. Highway in the state of Iowa. It crosses into Iowa over the Missouri River from South Sioux City, Nebraska, at Sioux City and runs approximately three-tenths mile (500 m) to an interchange with Interstate 29 where the road continues north as Wesley Parkway. Like all other state highways in Iowa, the route is maintained by the Iowa Department of Transportation.
U.S. Highway 75 (US 75) is a United States Highway in northwestern Iowa. It begins at the Missouri River on a bridge with Interstate 129 (I-129) and US 20. Immediately upon landing in Iowa from Nebraska, I-129 ends at an interchange with I-29. US 20 and US 75 continue around Sioux City on a four-lane expressway until US 20 exits to the east. US 75 heads to the north-northeast, parallel to the Floyd River, until Le Mars. There, Iowa Highway 60 (Iowa 60) continues northeastward on the expressway while US 75 heads due north. Near Hull, it is briefly overlapped by US 18. It leaves the state and enters Minnesota north of Rock Rapids.
Iowa Highway 7 was a state highway that existed from 1957 to 1968. It began at the interchange between Interstate 29 (I-29), U.S. Highway 20, and U.S. Highway 77 in Sioux City and traveled north to end at Iowa 3 west of Le Mars. The route of Iowa 7 was an original primary road in 1920, but then it was known as Primary Road No. 29 and later Iowa 29. When I-29 was designated to come through Iowa in the 1950s, Iowa 29 was renumbered Iowa 7. Through Sioux City, the highway was well traveled, especially near I-29 and the downtown area; the inverse was true at the rural northern end. Subsequently, Iowa 7 was removed from the primary highway system in 1968.
