US 71 en Kansas City Adds Another Interstate <p></p><p>You might have noticed a few changes while driving along US 71 Highway. For instance, you may have realized while traveling south that the sign for Grandview has been replaced with a sign for Joplin. This is but one of several changes that will take place over the next few months for US 71, which will soon become Interstate 49.</p><p> Mon, 17 Sep 2012 17:39:48 +0000 Susan B. Wilson 24526 at
