Cape Girardeau to Blacksburg Road Trip: Hidden Gems and Scenic Highways

This route from Cape Girardeau, Missouri to Blacksburg, Virginia spans approximately 710 miles, crossing four states via Interstates 55, 57, 24, 75, 40, 81, and US 460. The drive takes about 11 hours without stops, but the real value lies in the journey through the heart of America. You'll traverse the Mississippi River valley, the rolling hills of Kentucky, the Cumberland Plateau, and finally the Blue Ridge Mountains.

One specific fact: the section through the Cumberland Gap Tunnel at the Kentucky-Virginia border is one of the longest vehicular tunnels in the eastern US, boring through Pine Mountain for over a mile. This road trip is worth driving for the diverse landscapes alone, from the flat farmlands of Missouri to the winding mountain roads of Virginia.
