It is long, beginning at an intersection with Iowa Highway 44 in Panora and ending at the Minnesota state line north of Estherville. It continues north as Minnesota State Highway 4. The route was created on January 1, 1969, when several route designations were changed to match other states' route numbers. Before 1969, Iowa 4 was known as Iowa 17. ==Route description== Iowa Highway 4 begins at Panora at Iowa 44. It goes north and is briefly overlapped with Iowa Highway 141 north of Yale. It continues north until Jefferson, where it intersects U.S. Route 30 (US 30). It goes north, then turns west to enter Churdan, then turns north until meeting Iowa 175. At Iowa 175, the highway turns west, with Iowa 175, passing through Lohrville. It turns north west of Lohrville, and continues north through Rockwell City, where it intersects US 20. After a short concurrency with US 20, Iowa 4 continues north, and intersects Iowa 7. They overlap through Pomeroy, then Iowa 4 goes north through Pocahontas, which is where it intersects Iowa 3. North of Pocahontas, Iowa 4 meets Iowa 10 east of Havelock before passing through Mallard. Iowa 4 then goes north into Emmetsburg, where it meets US 18. Iowa 4 and US 18 continue west of Emmetsburg together, then Iowa 4 turns north to go through Graettinger. Iowa 4 then turns slightly northwesterly to go through Wallingford, before meeting Iowa 9 in Estherville. Iowa 4 then goes northeasterly out of Estherville before ending at the Minnesota border. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Iowa Highway 4」の詳細全文を読む スポンサード リンク
