In the background in this photo, taken on northbound Interstate 29 in September 2008, is Exit 43, the southern interchange for Interstate 229. I-229 forms a loop through the main part of St. Joseph, while I-29 bypasses much of the city. In the foreground is the 42.8-mile marker for I-29. The exit, though, is less than a thousand feet away. Maybe the exit number was rounded up.
