Iowa Route 12 is a route following the eastern edge of the Big Sioux River, which separates Iowa from South Dakota. The northern end is at Iowa Route 10 in Hawarden. The southern end is at Interstate 29 on the west side of Sioux City, just east of where the Interstate enters Iowa from South Dakota. Besides Hawarden and Sioux City, Iowa Route 12 only passes through Akron, Iowa, where it intersects Iowa Route 3.
Speaking of the intersection with Iowa Route 3, my photo of Iowa Route 12 comes from its meeting with Iowa Route 3 near Akron. The sign assembly shown faces west to tell eastbound travelers on Iowa Route 3 that Iowa Route 3 is about to join Iowa Route 12 south. It sits at the northern end of the concurrency between Routes 3 and 12, in Akron. The concurrency is very short and breaks up less than a mile to the south. I took this photo during my northern Iowa trip in September 2019. Back to the Iowa main page. Back to the home page.
