Business US 71 is parallel to much of the route of Missouri 249 in Joplin. While all of the eventual Missouri 249 route hadn't been constructed in December 2007, apparently there was enough of a need to point traffic over to Business US 71 from Missouri 249 at the Zora Street exit. Note the use of the US route shield on the destination sign.
