The differences between these markers and the usual Missouri state outline are subtle, but still quite noticeable with the state outline being rendered in more detail than usual. As is often the case for unusual outlines, these are markers used on a construction project in Kansas City. While the southbound Missouri 350 exit from Interstate 435 was being rebuilt, a temporary exit was constructed directly to the 63rd Street Trafficway. These signs point the way to Missouri 350 from its temporary endpoint on 63rd rather than the Blue Parkway.
These photos were taken in October 2003. The photo on the left was taken about halfway down the temporary ramp; the photo on the right, retouched to mitigate a shadowing effect, points the way right at 63rd Street.
