Several routes come together at the Grandview Triangle interchange in Kansas City. Also note the various types of markers on the signs. It appears that the Interstate 470 symbol uses button reflectors while the Interstate 435 doesn't. The marker for US 50 appears considerably newer than the markers for US 71. That's probably because US 50 was routed onto I-435 and I-470 several years after those freeways were built.
