Madison, IN to Myrtle Beach, SC: Ultimate Road Trip Guide

This route from Madison, Indiana, to Myrtle Beach, South Carolina, spans approximately 620 miles via I-65 S and I-74 E. A little-known fact: Madison's downtown, with its 19th-century architecture, was spared by the Civil War because it was a major Underground Railroad crossing—a detail that contrasts sharply with Myrtle Beach's modern beach resort history.

The drive typically takes 10-11 hours without major stops, but the real value lies in the intermediate landscapes: from the rolling hills of Kentucky to the Smoky Mountain foothills and finally the coastal plain. How to find the best stops and hidden gems between cities is key to transforming a monotonous drive into a journey of discovery.

Key highways: I-65 S from Madison to Louisville, then I-64 E to I-75 S, and later I-26 E and I-95 S near the coast. Peak seasons for this route are spring and fall when weather is mild and foliage adds color.

Fuel costs vary: expect average $3.20/gallon in Indiana and Kentucky, dropping to $2.90 in South Carolina. Total fuel cost for a full tank (assuming 25 mpg) around $80. Rest stops are frequent along interstates, notably at mile markers 40 and 80 on I-65 in Kentucky, and every 30 miles on I-95 in SC.

• Louisville, KY: Major fuel hub with stations near the I-65/I-264 interchange.
• Knoxville, TN: Multiple exits with cheap gas (Exit 108 off I-75).
• Asheville, NC: Higher prices but scenic stations along I-26.
• Florence, SC: Last major stop before Myrtle Beach; good for refueling.

Road quality: I-65 in KY is well-maintained but often under construction; I-75 in TN is smooth but can be congested near Knoxville. I-95 in SC is flat and straight but prone to heavy traffic during summer weekends. Toll Roads: None on this route. Avoid US-17 near Wilmington, NC if using I-40 as a detour; it adds time.
