Green rolling countryside on the southern end of this leg of I-44 morphs into wooded terrain as you gain altitude and climb into part of Mark Twain National Forest near Rolla. The four-lane, high-speed road shadows the Mother Road, headed north toward St. Louis. As it winds over the peaks and valleys beside Route 66, you’ll start seeing the land change again into the rocky landscape that’s filled with famous caverns.
