Iowa 92 begins on the
South Omaha Bridge above the
Missouri River with
U.S. Highway 275 (US 275) between
Omaha, Nebraska, and
Council Bluffs. It is a continuation of
Nebraska Highway 92, which stretches across Nebraska and is itself a continuation of
Wyoming Highway 92. Through Council Bluffs, the highways pass through the southern part of the city but just to the north of
Lake Manawa. At an interchange with
Interstate 29 (I-29), US 275 splits away from Iowa 92 and joins the Interstate Highway. The road continues east through
Pottawattamie County and into the communities of
Treynor and
Carson. Just east of Carson lies a
two-quadrant interchange with
US 59. later, the highway crosses the
East Nishnabotna River before it enters
Griswold. There, it meets
Iowa 48. The highway travels further east until it reaches an intersection with
US 71 at
Lyman. Iowa 92 turns north onto US 71 and the two highways
are overlapped for when Iowa 92 returns to its easterly course. At
Columbus Junction, the highway takes an
overpass above the downtown area and descends into the
Iowa River valley. Less than a mile north of the highway is the confluence of the Iowa and
Cedar rivers. It then passes just to the south of
Fredonia and continues east to an interchange with
US 61 at
Grandview. On the southwestern edge of Muscatine, US 61 and Iowa 92 turn off of the highway onto a bypass of city.
US 61 Business continues northeasterly from the intersection. The bypass forms a near-180 degree squared arc around the city. Near the halfway mark of the road around Muscatine, the two highways are joined by
Iowa 22. The highway then turns to the east, where it roughly marks the northern city limit. The bypass ends at an intersection with
Iowa 38 and the other end of US 61 Business. There, both Iowa 22 splits away from US 61 with Iowa 22 to follow Iowa 38 southward to the city's riverfront. At Washington Street, Iowa 22 turns east toward
Buffalo and
Davenport. Iowa 92, US 61 Business, and Iowa 38 head south and then southwest for a few more blocks. At the foot of the
Norbert F. Beckey Bridge, where Iowa 92 turns east towards
Illinois, Iowa 38 ends and US 61 Business continues south into downtown Muscatine. Iowa 92 crosses the
Mississippi River on the Beckey Bridge and continues in Illinois as
Illinois Route 92. ==History==
