^Rounding the bend from eastward to northward, past the exit to Iowa 163 in Des Moines, May 2019.
Interstate 235 is the freeway for accessing downtown Des Moines, Iowa. The Interstate highways in Des Moines form a rectangle that's four miles from north to south and ten miles from west to east; Interstates 35 and 80 extend outward from the northeast and southwest corners of the rectangle. Interstate 35 and Interstate 80 join together to flank the northern and western sides of Des Moines, along the northern and western lines of the rectangle. Interstate 235 forms the southern and eastern lines of the rectangle, serving downtown Des Moines, which sits near the southeast corner of the rectangle. As the rectangle is 10 miles long by 4 miles tall, Interstate 235 is 14 miles long.
A full list of exits with accompanying photos is shown below. First of all, though, here is the photo showing where I got my shield image for Interstate 235. The photo shows signage seen by travelers moving west on the portion of US Route 6 passing through an interchange with the north-south piece of Interstate 235. The first onramp that these travelers can access is off to the right just ahead, and it leads to Interstate 235 north. As this interchange, north of downtown Des Moines, lies just south of Interstates 35 and 80, it's fitting to include a guide sign to those other nearby Interstate highways, too. This photo was taken in September 2019, on the way home from my trip across northern Iowa (the outbound trip went across northern Iowa, and the return trip headed southeast to Des Moines).
Interstate 235's western beginning occurs at the interchange where Interstate 80 joins Interstate 35 north after coming in from the west. The westward continuation of the same pavement used by Interstate 235 carries Interstate 80 west toward Council Bluffs and Omaha, while ramps provide access to Interstate 35. Interstate 35 north leads drivers to Minneapolis and Chicago, because it also carries Interstate 80 east. Interstate 35 south is signed as the way to Kansas City...
