Interstate 435 forms a loop around the Kansas City metropolitan area. Missouri 291 intersects with the freeway near the northeast corner of the loop, with the result of what may seem to be an odd sign assembly. There's an explanation, though: I-435 continues as a north-south route for a few hundred feet north of this interchange, and then turns to become an east-west route, heading toward Kansas City International Airport.
You can also see a photo of the same sign assembly along with an accompanying destination sign.
This photo was taken in September 2008 on Missouri 291.
