Iowa Route 10 runs east-west in northwestern Iowa, from Hawarden to a point just north of Pocahontas. A north-south bridge crosses the Big Sioux River to form the western terminus of Iowa Route 10 just north of Hawarden. The generally east-west South Dakota Highway 46 bends south to cross the river and become Iowa Route 10, and in Hawarden, Iowa Route 10 turns back easterly at a junction with Iowa Route 12. The eastern end of Iowa Route 10, on the other hand, is an intersection with Iowa Route 4 north of Pocahontas. The route of Iowa Route 10 is an intermediate route, south of US Route 18, but north of Iowa Route 3.
My photo for Iowa Route 10 comes from the highway's junction with Iowa Route 143, halfway between the towns of Granville and Paullina. This photo was taken as September 2019's trip to northern Iowa. The assembly depicted faces west to eastbound travelers on Iowa Route 10.
