Iowa Highway 92 (Iowa 92) is a state highway that runs from east to west across the state of Iowa. Iowa 92 is 279 miles (449 km) long. It begins at the Missouri River in Council Bluffs, where it is a continuation of Nebraska Highway 92. It stretches across the state and serves to roughly demarcate the southern one-third of Iowa. It ends at the Mississippi River in Muscatine where it continues into Illinois as Illinois Route 92. In 1939, Iowa 92 replaced the original Iowa 2 in its entirety.

Route description

Mississippi River at Riverside Park in Muscatine, Iowa. The flooded river in this June 2013 photo has closed the park, and caused Business US 61 and Iowa Highway 92 to be detoured to higher ground.

Iowa 92 eastbound in Columbus Junction, approaching an intersection with Iowa 70.

From its eastern terminus is Muscatine, Iowa 92 immediately becomes concurrent with Business U.S. Highway 61 and follows Business 61 southbound in a southwesterly direction towards the southern terminus of Business 61 near the Muscatine Industrial Connector where they meet U.S. Highway 61. After that intersection, Iowa 92 is then concurrent with U.S. 61 southbound for about 11 miles (18 km) and crosses the border from Muscatine County into Louisa County. Near the Louisa County town of Grandview, Iowa 92 splits off from U.S. 61 at a new interchange that opened in December 2017, and then heads west. It passes by the Louisa County town of Fredonia, crosses the Iowa River and passes through Columbus Junction. A few miles later, Iowa 92 crosses the border from Louisa County into Washington County. Iowa 92 intersects U.S. Highway 218 and Iowa Highway 27 at a freeway interchange before passing through Ainsworth. After 7 more miles, it enters the city of Washington, which is the county seat for Washington County.

At the west end of Washington, Iowa 92 overlaps Iowa Highway 1 for a few miles to the north, and then Iowa 92 splits off to the west again, passing through the small Washington County village of West Chester. A few more miles and Iowa 92 crosses the border from Washington County into Keokuk County. In Keokuk County, Iowa 92 becomes concurrent with Iowa Highway 149 as it travels into the Keokuk County Seat of Sigourney. After Sigourney, Iowa 149 splits off to the south and Iowa 92 continues westbound, passing its interchange with Iowa Highway 21 and crossing the border from Keokuk County into Mahaska County.

A few miles after the Keokuk-Mahaska county line, Iowa 92 enters the city of Oskaloosa, which is the county seat for Mahaska County, and intersects with Iowa Highway 23, then U.S. Highway 63, and finally Iowa Highway 163. After Oskaloosa, Iowa 92 continues its westbound journey, crossing the border from Mahaska County into Marion County. In Marion County, Iowa 92 passes though a small town called Harvey before reaching the city of Knoxville, which is the county seat of Marion County. Iowa 92 bypasses the southern end of Knoxville as a four lane freeway, passing the interchanges of Iowa Highway 5 and Iowa Highway 14. Iowa 92 overlaps Iowa 5 from the interchange in Knoxville to the point where Iowa 5 splits off to the north about 9 miles (14 km) west of Knoxville. Also at this point is the junction of county road S45 (formerly Iowa Highway 181) which heads southbound from the Iowa 5/Iowa 92 junction toward Melcher-Dallas).

After crossing the border from Marion County into Warren County, Iowa 92 bypasses a small village called Beech and passes through two more towns, Sandyville and Ackworth before reaching the county seat of Warren County, the city of Indianola. It intersects with U.S. Highway 65 and U.S. Highway 69 in Indianola, which are both concurrent with each other and are both north–south routes as well. After Indianola, Iowa 92 continues westbound and passes by Martensdale and its intersection with Iowa Highway 28 and 3 miles (4.8 km) after that, meets its interchange with Interstate 35, which is one of two major north–south Interstate highways that traverses the state of Iowa.

Immediately after Interstate 35, Iowa 92 continues across the border from Warren County into Madison County and passes through 2 small towns, Bevington, and Patterson. After that, Iowa 92 bypasses the city of Winterset which is the county seat for Madison County. At Winterset, Iowa 92 meets U.S. Highway 169 and overlaps U.S. 169 southbound for a couple of miles to the west and south, bypassing the northern and western edges of Winterset, before they split off, and U.S. 169 continues to go south while Iowa 92 continues its journey westbound.

Iowa 92 east of Greenfield

A few miles after Winterset, Iowa 92 crosses the border from Madison County into Adair County. Iowa 92 then passes the village of Stanzel before finally reaching the city of Greenfield, which is the county seat for Adair County. Iowa 92 intersects with Iowa Highway 25 in Greenfield. After Greenfield comes a smaller town called Fontanelle and a few miles after that passes just north of a town called Bridgewater, then Iowa 92 crosses the border from Adair County into Cass County.

In Cass County, Iowa 92 intersects with Iowa Highway 148 just outside the small town of Massena. After that, Iowa 92 bypasses another small village, Cumberland and then meets U.S. Highway 71, at which point Iowa 92 turns southbound and overlaps U.S. 71 for 2 miles (3.2 km). After 2 miles (3.2 km), U.S. 71 continues south and Iowa 92 splits off to the west again, and heads toward Griswold. In Griswold, Iowa 92 passes its intersection with Iowa Highway 48 and immediately after Iowa 92 exits Griswold, it crosses a county line for a final time in the State of Iowa, from Cass County into Pottawattamie County.

After 13 miles (21 km) of travel, Iowa 92 intersects with U.S. Highway 59. After the U.S. 59 interchange, Iowa 92 passes through the south edge of Carson, and continues on westbound though the village of Treynor and a few miles after that, enters the city of Council Bluffs. In Council Bluffs, Iowa 92 intersects U.S. Highway 275 and Interstate 29, Iowa's other major north–south Interstate. Iowa 92 and U.S. 275 are then concurrent west of Interstate 29. A few more miles through Council Bluffs and Iowa 92, still concurrent with U.S. 275, crosses the Missouri River, which is also the state border line from Iowa to Nebraska, the county line from Pottawattamie County to Douglas County, and the city line from Council Bluffs to Omaha, at the South Omaha Bridge.

At this point Iowa 92 comes to its western terminus and meets Nebraska Highway 92. Nebraska 92 and U.S. 275 continue to overlap through the city of Omaha, and out to the west of the city, until they split up in western Douglas County. Nebraska 92 then journeys across Nebraska as an east–west highway, all the way to the Wyoming border, where it meets Wyoming Highway 92 at its western terminus.

History

Iowa Highway 92 was designated on February 1, 1939, replacing the former Iowa Highway 2 in its entirety.^[2] Iowa 92's designation created a continuous Highway 92 from North Platte, Nebraska to La Moille, Illinois.
