AS Highway 18 ( USÃ, 18 ) is a US east-west northwest highway in the state of Iowa. Like all state highways in Iowa, it is managed by the Iowa Department of Transportation (Iowa DOT). It enters the country by traversing the Big Sioux River between Inwood and Canton, South Dakota. It travels 311 miles (501 km) and connects Spencer, Mason City and Charles City. The highway leaves the country via the Marquette-Joliet Bridge over the Mississippi River at Marquette. Prior to becoming the U.S. Highway, the following 18 US routes are known as Main Street no. 19 and Pike National Park .

Route description
US $ 18 starts at Big Sioux River about 2 miles (3.2 km) east of Canton, South Dakota. It runs east through rural Lyon County, in the northwest corner of the state. At Inwood, he meets Iowa, 182, which provides access to Sioux Falls, South Dakota, through IowaÃ, 9 and South Dakota Highway 42. US $ 18 turns south at Inwood and heads to Sioux County. The highway crosses the Rock River on the way to Rock Valley and Hull. West of Hull, at Perkins, US $ 18 juts south along US $ 75 before turning east again closer to Hull. The highway continues east toward Sheldon.
When crossing into O'Brien County on the western edge of Sheldon, US $ 18 cuts the business circle of IowaÃ, 60. Both routes head east toward the diamond junction with IowaÃ, 60 on the east side of the city where the business circle ends. The highway is roughly parallel to the Dakota, Minnesota, and Eastern Railroad (DM & E Railroad). At Sanborn, US $ 18 briefly overlaps by US $ 59, which joins from the north and goes south. Continue east, past Hartley and then enter Clay County. North of Spencer, he cuts US 71 and two routes heading south along through the city. On the south side of Spencer, two routes to T junction and each route go in the opposite direction - US $ 18 to the east and US 71 to the west.
East of Spencer, US $ 18 passes Ruthven in Palo Alto County. Between Ruthven and Emmetsburg, it joins Iowa 4 from the north. Both routes split again in Emmetsburg because Iowa 4 leads south. US 18 goes east, briefly southwards to enter the Cylinder. Curve route back east on DM & amp; E Railroad. An intersection with IowaÃ, 15 near Whittemore marks the Palo Alto-Kossuth county line. Iowa 15 follows US 18 for 1 mile (1.6 km) before it is split north. On the north bank of Algona, the highway meets US.19. In the eastern county of the county, divided by Hancock County, is the crossing with Iowa 17, which marks the northern end of the route.
In Hancock County, route past Britt before meeting US $ 69 1 mile (1.6 km) west of Garner; two highways split in Garner. East Garner, the route takes the north-northeast route as it passes through Ventura and the northern Clear Lake beach skirt. Near the northeastern shore of the lake, it enters the town of Clear Lake, where it meets Interstate 35 (I-35). Iowa, 122, and Route 18 US Business (USÃ, 18Ã, Bus.) Leading east from the intersection with the interstate. The US $ 18 traffic follows south direction I-35 to 4 miles (6.4 km). Iowa 27, the Avenue of the Saints highway, which until now follows I-35 south now follows USÃ, 18 to the east. Both routes, now on a four-lane highway, controlled highway, follow the path leading south of Mason City. They meet US $ 65 and US $ 18 Bus. at exit 186.
In the Floyd county line, the US and Iowa 27 became a limited access road and a slight corner to the northeast, past Rudd. At Floyd, the two routes were joined by USC 218. The three routes headed south along the Charles City bypass road. They cut IowaÃ, 14 on the west side of the city and took a 90-degree curve to the east. On exit 218 of the highway, US 18 leaves US $ 218 and Iowa 27, which continues southeast toward Cedar Falls-Waterloo. US 18 immediately head north to Charles City with US 218 Bus. Both routes meet the northern end of Iowa 14, and US 18 splits east to cross the Cedar River.
Head east again, route into Chickasaw County and pass Bassett on the way to New Hampton. It meets US $ 63 in a four-lane bypass on the west side of the city. Both routes to the south as far as 8 miles (13 km), splitting at the 196 foot intersection which is also the eastern end of Iowa 346. The route turns into a trip east through Fredericksburg.
Continuing to the northeast, US 18 did not enter another community as far as 20 miles (32 km) to reach West Union in Fayette County. At West Union, he cut Iowa 150. East of the city, across to the Driftless Area, an area untouched by glaciation during the last ice age. The route turns northeast through Clermont and then north to meet US 52 in Postville in southern Allamakee County. Both routes head east through Postville and turn south to Clayton County. Near Froelich, US $ 52 leaves south to Dubuque. Head northeast toward McGregor and Marquette, his business circle passes through towns while the main line skirts around them.

History
Before and rest of U.S. Highway System set on November 11, 1926, US 18 was known by two names in the state. It was first known as Main Street no. 19, assigned to the route when the Iowa State Highway Commission published the first state highway map in 1919. The route is also called Pike National Park, which begins in Yellowstone National Park and ends in Madison, Wisconsin, covering all Main Street No. 3. 19 in the state. Pike was registered on April 29, 1920. The name of Pike National Park fell unused after the highway became US $ 18.
In 1927, most routes were paved, while the rest were rocky. All O'Brien County and 80 miles (129 km) between Algona and Charles City are paved. Within seven years, the gap between O'Brien County and Algona finished that creates 160 miles (257 km) of continuous path. For the same seven years, the route from the West Union to the Mississippi River and all Main Street No. 59, which includes a 7-mile-long (11 km) overlap of US $ 18 near New Hampton paved. Primary Road No. 59 now known as US 63. At the beginning of World War II, the only remaining portion of the unsealed $ 18 US was 11 miles (18 km) west of Rock Valley in Sioux County. That last part will not be completed for another ten years.
Before 1932, the only way a vehicle that traveled US $ 18 could cross the Mississippi River was by ferry. That changed when the same suspension bridge was built to cross the river between Marquette and Prairie du Chien, Wisconsin. Built in 1931-1932, each bridge measures 450 feet (140 m) across the main channel of the river and is divided by the 2,000 foot (610 m) island-wide crossing route. The first car to cross the bridge did so on March 7, 1932. Users of the bridge had to pay the toll until July 15, 1954. The bridge was still in use for another twenty years, when they were replaced by the Marquette-Joliet Bridge. In 1988-1989, a bypass was built around McGregor so US $ 18 could connect directly to the Marquette-Joliet Bridge. The previous short walk has provided access to and from the bridge. The long alignment of routes into Bus US.18.
During the late 1990s, construction began in the corridor of Avenue of the Saints near Mason City. The newly controlled access facility was built south of the eastern city to Rudd. On December 5, 1999, part of the expressway was opened and US $ 18 was released back to the new road. The old alignment became Iowa Highway 122. By the end of the following year, the four-lane highway extended to Charles City. In 2003, a toll road carrying US $ 63 was built around New Hampton. US $ 18 diverted to the highway and the western tip of Iowa 24 was transferred to the intersection of US $ 63/18.
