Iowa Highway 117 is a north–south route in Jasper County. The length of the highway is 18 miles (29 km). In addition to serving several communities directly, Highway 117 also provides a shortcut between U.S. Route 65 and Interstate 80 east of Des Moines.
Route description
Iowa Highway 117 begins at a partial cloverleaf interchange with Iowa 163 on the edge of Prairie City. For its first mile (1.6 km), Iowa 117 runs west-to-east along Second Street, a former alignment of Iowa 163. At its former southern end, State Street, it turns north approaching the center of town. North of Prairie City, Iowa 117 travels due north for 5 miles (8.0 km) until Colfax.[1]
At Colfax, Iowa 117 turns west onto State Street. Outside of Colfax, State Street is Jasper County Road F48, which connects Mitchellville and Newton. After Lua error in Module:Convert at line 452: attempt to index field 'titles' (a nil value)., the highway turns north towards downtown Colfax where it crosses an Iowa Interstate Railroad line and the South Skunk River.[1] One mile north of the river is a diamond interchange with Interstate 80 and U.S. Route 6.
North of Colfax, Iowa 117 passes through rolling farmland with houses dotted along the road. Three miles (4.8 km) from Mingo, the highway begins curving to the north and west, parallel to Indian Creek. The last four miles (6.4 km) of Iowa 117 travel on creek bottoms, still adjacent to Indian Creek. Just 500 yards (460 m) from its northern end, Iowa 117 crosses Indian Creek one final time.[1][2] It ends a four-way intersection with U.S. Route 65 and Iowa Highway 330. The dominant road is a four-lane expressway connecting Des Moines and Marshalltown. South of the Iowa 117 intersection, the expressway is US 65 while north or the intersection is Iowa 330.
History
Between July 1, 1920 and December 11, 1936, the road currently designated as Iowa Highway 117 was designated as Iowa Highway 64, while the original Iowa Highway 117 served as a highway between Anamosa and Sabula. The two highway designations were swapped on December 11, 1936. The highway originally extended northward to Colo until 1940, when the segment between the current northern terminus and Colo was replaced by US 65.
In 2002, the northern terminus intersection was reconstructed. Previously, the roads which met at that point intersected one another at a sharp angle.[3] The 2002 reconstruction changed this so the involved highways intersected at right angles to each other.[4]
Major intersections
The entire route is in Jasper County.
